What is it???

Introduction to Chemical Reactions

What is chemical reaction? I got this questions a lot by fellow classmates. Honestly, I don't know. Acoording to Wikipedia "A chemical reaction is a process that leads to the transformation of one set of chemical substances to another." Myself believe that chemical reaction is not complicated. Chemical reactions are everywhere. They react together and are around us. It will be easier if I show you this....

Differences between Chemical Reactions & Physical Reactions

Two things important about chemical reaction are:

- Chemical reaction is irrversible -> Reversible reactions are physical reaction

Eg: Frying egg -> You cannot turn the egg into its form shape

-> Chemical reaction

Water vapour from boiling water -> After leaving it for a while, it will turn into solid (water)

-> Physical reaction

- Chemical reaction always produce new substances.

Eg: Sodium + Hydrochloride Acid -> Sodium Chloride + Hydrogen

Na + HCl -> NaCl + H2

Chemical Reactions Song

The funny thing is we never realize the reaction even if it is in front of our face. We are made of elements, we are made of elements which react with each other. Reactions are not as hard as people made it out. Have you ever wondered why the iron rust? Have you ever thought why water and put out fire? They are all chemical reactions.

As the matter of fact, this topic is so interesting that I can keep talking about it forever. But I will catch up with you guys later til' the next blog.

By the way, if you want to know more about chemical reactions, check out this video. That is the coolest teacher I've ever seen. He made a video of chemical reactions' song.
