- This article provides a complete list of all the names of these figures. It is also important to know the bond angles of these figures. Another important topic is the shape of the separate orbitals. The s orbital has a sphere shape, the p is dumbbell shaped. The rest of the shapes and allowed quantum numbers are explained here. Stoichiometry There is not much to say about this topic, either you know it or you don't. This topic is used frequently in the test and you should have a solid knowledge of these three things: 1. How to find the empirical and molecular formula for a compound 2. How to find the percent composition of a compound 3. How to determine the mass of a compound yielded using a balanced equation You will also need to know how to use Avogadro's number correctly 6.
- Some questions may ask you to find the amount of atoms or molecules in something, in which case you need to know that there are 6. The first is that you know what a phase diagram is and what it represents. It represents phase changes in an element or compound under different temperatures and pressures: the x axis is temperature and the y axis is pressure. A phase diagram usually has a nice prong shape, with the middle being the liquid phase, the left side being the solid phase, and the bottom is the gas phase. It is also important to know the names of phase changes sublimation, condensation, etc. A phase diagram. The red, blue, and green solid lines form a prong shape. Usually this will appear as a series of representations of these types of matter, and it will ask you to choose the correct one.
- If you cannot visually tell between these things, it will be helpful to look at the link below. The Difference Between Mixtures and Pure Substances Energetics The most importance thing about energetics is knowing your equations and strategies! Your value for the specific heat has units, which should match your other variables. Specific heat values will be given to you, of course. It is also good to know how to calculate bond energy. It will not be discussed here, but here is a link for more information. Redox There will be at least one redox-related question on the exam.
- Here are a few things to keep fresh in mind. How to determine oxidation numbers remembering that certain elements, like oxygen, sulfur, hydrogen, and flourine have set oxidation numbers How to determine reduced and oxidized elements in a reaction and their agents! How to properly balance a reaction performed in either basic or acidic solution though this is less likely to appear, it is good to know if continuing on with chemistry And on that note, know the difference between a "solution" and a "solvent"! A solvent dissolves in a solute, and creates a solution. Here is a list of what you might see. Questions about physical properties of the transition metals. For example, transition metals usually turn vibrant colors when ionized. Questions about atomic radii. This is where you NEED to know the trend. The smaller elements are in the upper right corner while the largest are in the bottom left corner. Ions are tricky, this is where you need to compare the amount of protons in the atom and the amount of electrons.
- If an atom has more protons than electrons, then the nucleus is more effective at pulling electrons in, making it smaller. Questions about electronegativity. The trend here is, the smaller the atom, the more electronegative it is. This is also good to know if you get a question about polarity. There needs to be an uneven spread of polar bonds in a molecule in order to be polar. Laboratory Chemistry 1. Knowing your equipment. Sure, you know what a beaker is, but how about a mass spectrometer? Knowing your significant figures. This is a huge deal in any science. If you don't know this by now, you better get going! You also need to be fknow how many significant figures common lab equipment can read to. A buret measures to two decimal places, by the way. Knowing the difference between precision and accuracy. Let's say your target number is If you get You may also be asked to calculate percent error.
- Mindfulness techniques, if practiced by students, can be easily called upon if they feel overwhelmed. Last year saw the biggest rise in the number of teenagers, aged 12 — 15, receiving counselling from Childline for exam stress — up by 21 per cent from the previous year. What is mindfulness? Instead of being overwhelmed by thoughts, you are able to manage them better and accept them without judgement. The wide-ranging benefits of mindfulness training There is mounting evidence that mindfulness has measureable effects on many aspects of health. According to the British Journal of Psychiatry , school based interventions have impactful positive outcomes on wellbeing: reducing anxiety and stress as well as improving behaviour. Neuroscientists have found that long-term mindfulness practice alters the structure and function of the brain to improve the quality of both thought and feeling. Mindfulness helps to achieve the goal of quietening the mind and heightening awareness.
- During a recent ACS Hillingdon Wellness Week, we spent ten minutes every day practicing guided meditations with our students in class. At the end of the week, teachers cited calmer classes with most students also saying they felt re-focused and much less stressed. This mirrors the results of a Mindful Schools study in which 83 per cent of teachers saw improved focus amongst students who had undertaken mindfulness training. Additionally, 89 per cent also claimed their students were regulating their emotions more effectively, while three quarters claimed that their students were behaving with greater compassion. A large proportion, 79 per cent, of teachers also cited increased engagement in the classroom.
- Meditation Guide students through a meditation. Meditation inspires students to concentrate on their senses and breathing, clearing headspace to think and regulate their emotions. Students may find meditations challenging to begin with, but with practice, they will find it becomes much easier. The Five Senses Drill Similar to the guided meditations, a three-minute breathing exercise can help students to re-focus their attention and restore focus and calm. Students feeling anxious can add in their mental, physical and emotional states into the app which will curate personalised meditations based on their results. Switch off your tech Taking a step back from technology will also benefit them in the long run, so encourage young people to avoid sleeping with their phones beside their beds, and advise them to cut down mobile phone usage particularly in the evenings and at night.

Stick to a sleep routine Encouraging students to get up at the same time each morning, eating healthily, and engaging in regular physical activity, will also help to aid sleep. Getting enough sleep is one of the most powerful ways we can protect ourselves from stress and anxiety. Get creative Engaging in a relaxing and creative activity can be very beneficial for students, especially during a stressful period, such as during the exam season.Preparing For The American Chemical Society General Chemistry Exam (Part I)
This could include colouring intricate patterns, sculpting, or simply sketching. Repeating this phrase over a series of days, weeks and months, will help drown out any negative thoughts and will foster a positive attitude. Teaching mindfulness gives students the crucial tools to deal with the pressures of life. The ability to be able to step back, reflect thoughtfully and truly focus is a skill that can help students deal with stress and pressure, both in and out of the classroom. Long term, practising mindfulness cultivates a greater sense of perspective, within the school gates and beyond. We believe it makes complete sense to incorporate it into school life, and beyond, so students can draw upon it whenever they wish to.- Because chemistry and other science courses are cumulative topics, your finals usually will be too—and that can make the pressure feel even worse. Space your studying The worst thing you can do is wait until the last minute to study for a cumulative final exam, or for any exam for that matter. Even giving yourself a week can be a challenge. Your brain is much better at absorbing information in short bursts rather than long cramming sessions.
- If you haven't been doing so all along, the best place to start your final exam preparation is by going over past work. With exams soon approaching, the best thing to do is keep calm. Descending into a stress spiral only wastes precious time and brainpower. Look at what material will be covered on the final and make a list of important concepts. There may not be enough time to completely learn every concept at this point, but you may be able to understand aspects much better, which could boost your performance. Study smarter, not harder Science has shown over and over again that simply rereading your notes is just about the single worst way to study. If you are taking an ACS exam, you can purchase practice exams and study guides. Otherwise, check with your professor or with other students who have already taken the course. Another helpful tactic is to prioritize things you already have a partial grasp of and try to strengthen your skills and understanding.
- Generally, each chapter covered on a cumulative final has three to six important concepts. Figure out what these are and make sure you look over each one. Get info in advance Before going into finals, find out the test format multiple choice, free response, etc. In general, the more information provided on the exam, the more the professor is testing your understanding of the material, rather than your memorization of basic facts, an important clue in where to focus your studying efforts. It's also a good idea to talk to your professor if you are stuck on anything. Although meeting earlier in the course is better, your professor would much rather you visit last-minute and succeed than struggle alone and fail.
7 Mindfulness Tips To Help Students Deal With Exam Stress | ACS International Schools
Even if you can study for eight hours straight, make sure to stop every hour or so for a break—get up, walk around, have a snack, or do something else for about minutes to give your brain a rest and reduce your stress level. Conquering exam day On exam day, good mental preparation starts with good physical preparation. Instead, bring your confidence on the day of the exam to stay focused on your work.- As you go through the exam, answer all the questions you feel super-confident about to get those easy points. For free-response questions, try to write something down to get partial credit. Notes for next year Staying on top of your understanding all semester is the very best way to rock midterms and finals. When next semester rolls around, you can reduce some of the end-of-semester stress you may be feeling right now by working on assignments, projects, and papers as they are assigned. If a final exam is cumulative or covers an entire course sequence, begin studying content early in the semester. Set a goal and try to stick with it. And be sure to review your test, quizzes, and graded assignments as you get them back.
- Then you can spend the last few weeks of the semester reviewing the material that you find particularly challenging. Final exams can be exhausting and stressful, but you can power through them by studying early, using your resources wisely, and creating a plan to make the process much more manageable.

- Finding breast cancer early and getting state-of-the-art cancer treatment are the most important strategies to prevent deaths from breast cancer. Getting regular screening tests is the most reliable way to find breast cancer early. The American Cancer Society has screening guidelines for women at average risk of breast cancer, and for those at high risk for breast cancer. What are screening tests? The goal of screening tests for breast cancer is to find it before it causes symptoms like a lump that can be felt. Breast cancers found during screening exams are more likely to be smaller and still confined to the breast.
- The size of a breast cancer and how far it has spread are some of the most important factors in predicting the prognosis outlook of a woman with this disease. American Cancer Society screening recommendations for women at average breast cancer risk The COVID pandemic has resulted in many elective procedures being put on hold, and this has led to a substantial decline in cancer screening.
- These guidelines are for women at average risk for breast cancer. See below for guidelines for women at high risk. Women between 40 and 44 have the option to start screening with a mammogram every year. Women 45 to 54 should get mammograms every year. Women 55 and older can switch to a mammogram every other year, or they can choose to continue yearly mammograms. Screening should continue as long as a woman is in good health and is expected to live at least 10 more years. All women should understand what to expect when getting a mammogram for breast cancer screening — what the test can and cannot do.
- Clinical breast exams are not recommended for breast cancer screening among average-risk women at any age. Mammograms Mammograms are low-dose x-rays of the breast. Regular mammograms can help find breast cancer at an early stage, when treatment is most successful. A mammogram can often find breast changes that could be cancer years before physical symptoms develop. Results from many decades of research clearly show that women who have regular mammograms are more likely to have breast cancer found early, are less likely to need aggressive treatment like surgery to remove the breast mastectomy and chemotherapy, and are more likely to be cured.
- Mammograms are not perfect. They miss some cancers. And sometimes a woman will need more tests to find out if something found on a mammogram is or is not cancer. This is called overdiagnosis. It's important that women getting mammograms know what to expect and understand the benefits and limitations of screening. Many studies have found that 3D mammography appears to lower the chance of being called back for follow-up testing. It also appears to find more breast cancers, and several studies have shown it can be helpful in women with more dense breasts. A large study is now in progress to better compare outcomes between 3D mammograms and standard 2D mammograms. It should be noted that 3D mammograms often cost more than 2D mammograms, and this added cost may not be covered by insurance. The American Cancer Society breast cancer screening guidelines consider having had either a 2D or 3D mammogram as being in line with current screening recommendations. The ACS also believes that women should be able to choose between 2D and 3D mammography if they or their doctor believes one would be more appropriate, and that out-of-pocket costs should not be a barrier to having either one.
- Clinical breast exam and breast self-exam Research has not shown a clear benefit of regular physical breast exams done by either a health professional clinical breast exams or by women themselves breast self-exams. There is very little evidence that these tests help find breast cancer early when women also get screening mammograms. Most often when breast cancer is detected because of symptoms such as a lump , a woman discovers the symptom during usual activities such as bathing or dressing. Women should be familiar with how their breasts normally look and feel and should report any changes to a health care provider right away.
American Cancer Society Guidelines For The Early Detection Of Cancer
While the American Cancer Society does not recommend regular clinical breast exams or breast self-exams as part of a routine breast cancer screening schedule, this does not mean that these exams should never be done. In some situations, particularly for women at higher than average risk, for example, health care providers may still offer clinical breast exams, along with providing counseling about risk and early detection. And some women might still be more comfortable doing regular self-exams as a way to keep track of how their breasts look and feel.- American Cancer Society screening recommendations for women at high risk Women who are at high risk for breast cancer based on certain factors should get a breast MRI and a mammogram every year, typically starting at age This is because although an MRI is more likely to detect cancer than a mammogram, it may still miss some cancers that a mammogram would detect. Most women at high risk should begin screening with MRI and mammograms when they are 30 and continue for as long as they are in good health. But a woman at high risk should make the decision to start with her health care providers, taking into account her personal circumstances and preferences.

These tools give approximate, rather than precise, estimates of breast cancer risk based on different combinations of risk factors and different data sets. Because the different tools use different factors to estimate risk, they might give different risk estimates for the same woman. Two models could easily give different estimates for the same person. Risk assessment tools that include family history in first-degree relatives parents, siblings, and children and second-degree relatives such as aunts and cousins on both sides of the family should be used with the ACS guidelines to decide if a woman should have MRI screening. The use of any of the risk assessment tools and its results should be discussed by a woman with her health care provider.Preparing For The American Chemical Society General Chemistry Exam (Part I) - Owlcation - Education
