Chemistry is a branch of science that studies the matter, its properties, composition, and reactivity. It also study how and why substances form and separate to form another substance. Chemistry is often feared by students or considered as boring by others but the truth is chemistry is a mystery. Those who understand the subject love it those unable to understand simply ignore it. This blog post will introduce you to the other side of Chemistry.
