Chemistry is a very diverse field. There are many different branches and ways of exploring the chemicals themselves and how the world is made by combinations of them. Answer and Explanation: Some of the main branches of chemistry are:
Chemical Classification:A chemical category is a group of chemicals whose physical, toxicological, environmental properties are likely to be similar. They are often a result of the chemical structural similarity.Answer and Explanation: There are several classification methods for chemicals. Some of the ...
Chemistry is the study of matter and how it changes. Matter is everything that has mass and takes up space, like the air we breathe, the water we drink, and the objects we use every day. Chemistry helps us understand what things are made of and how they interact with each other. For...
