Chemistry and Life This is basically the first multiple-choice question in the chemistry part of the comprehensive college entrance examination. The applications of the materials in the options in real life are all in the textbooks, so you should read them carefully, such as the comprehensive utilization of coal, oil, natural gas and seawater resources. There are not many chemical equations and ionic equation's equations in the book, but many of them are the key points. The chemical equations appearing in textbooks are basically accompanied by experiments. For these experiments, we should pay attention to the influence of drug order and the influence of excessive drugs.

How to get the fastest score in chemistry multiple-choice questions? 1, return to the textbook. In fact, every time the test is finished, the test sites involved in the test paper can be found in the book. If your grade in chemistry is average, I suggest you brush less questions and focus on basic grades, so that your promotion will be faster.

2, the back must be backed. For example, to judge the redox reaction, it is necessary to recite the redox sequence table. In possible redox reactions, the oxidizability of oxidant is stronger than that of oxidation product, and the reducibility of reductant is stronger than that of reduction product. When the oxidant is insufficient, the substances with strong reducibility are oxidized first, and vice versa.

3. Regular targeted training. For the exam-oriented education we are facing now, it is inevitable to do the questions, but what we need to pay attention to is to do the right questions, do the questions well and have targeted exercises.

Chemistry multiple-choice questions answering skills 1, list special cases, and quickly arrange options.

Multiple-choice questions in college entrance examination often examine special situations in general laws and require candidates to be familiar with special situations. For some topics such as concept judgment and proposition judgment, if you can't judge directly from the front, you can list counterexamples and special cases to quickly judge whether the options are right or wrong.

2, clever use of assumptions to static braking.

Many factors (such as temperature, hydrolysis equilibrium, concentration or pressure) are sometimes involved in answering questions about the movement of four equilibria (chemical equilibrium, ionization equilibrium and precipitation-dissolution equilibrium). For this kind of problem, we can use the hypothesis method, assuming that other factors remain unchanged, and then judge the influence of the change of the first factor on the result, and then judge the influence of the change of the second factor on the result, and then get the correct answer.
