Chemistry is an important subject in science subjects that reconciles and thinks. It is easy to learn and learn for a long time. So learning chemistry is very important.
Consolidate the basics
In the process of learning chemistry, you must memorize the basics. For example, we only have the valence of each element. In order to learn the balance equation, only by mastering the characteristics of acid-base salt can lay the foundation for the later learning of the neutral equation.
The premise of memory is to learn to understand
The memory of chemistry is different from other disciplines. We are not simply remembering It will be possible to have a back-to-back meeting. It requires an in-depth understanding. Only by understanding the relationship between chemical elements and understanding the principles of each chemical reaction can we remember forever and lay the foundation for future study.
Important chemistry experiment
Chemical experiment is the soul of chemistry, we must do the experiment Learn to observe the experiment, pay attention to the experimental conditions, observe the experimental results, record the experimental process, etc., in order to truly grasp the connotation of the experiment, in the future study, the knowledge can be coherent and long-lasting.
Learning chemistry knowledge is all-inclusive
When we study any topic in chemistry, we must have knowledge of chemistry. Mastering all aspects, such as the burning of magnesium strips, we not only have to see “a dazzling white light”, but also to see if there is solid formation on the asbestos net. Only by mastering each experiment can you truly understand the nature of chemistry.
Mastering the appropriate solution method
If we are answering multiple choice questions, we should choose the exclusion method, Comparative analysis method, direct selection method, calculation method, inference method, etc.
Mastering Common Knowledge Points for Calculation Questions
When chemistry is used for calculations, we generally use: quality Conservation laws, valence calculations, chemical equations, etc., need to master these basic chemical laws, we can solve the problem of chemical calculations.
Chemical experiments, we need to master the basic methods
Chemical experiments, we generally use the following methods: absorption Method (for gas purification), displacement method (de-doping), precipitation method (impurity precipitation removal), and the like.
Classification of knowledge points
Chemical knowledge is scattered, we should be complicated during the process of learning Knowledge is classified and summarized to form its own memory network, such as summarizing our commonly used carbon dioxide, nitrogen, and hydrogen.
Good at summarizing chemistry knowledge
If we are in memory experiments, there are some fixed principles that are chemical experiments. Required knowledge, such as: placed on the left side of the tray balance, placed on the right side of the weight, that is, “left object right code”; solid medicine placed in a jar, liquid medicine placed in a thin mouth bottle.
