Stoichiometry

Hello fellow subscriber... and viewers! Today we learned about the Quantitative Chemistry - Stoichiometry.

....What? What is Stoichiometry? WELL it is a branch of chemistry that deals with the qualitative analysis of chemical reactions.

To understand Stoichiometry, our teacher reviewed us on the 6 types of reactions (not including complex reactions that doesn't go under the 6 common reactions). This is what we learned in grade 10; last year.

Ok, so there are 6 common types of reactions
1) Synthesis (Formation)
2) Decomposition
3) Single Replacement (SR)
4) Double Replacement (DR)
5) Neutralization
6) Combustion

Here is a breakdown of each reaction:
1)Synthesis : Basically a reaction to make compunds; so the equation would be-
A+B=AB

2)Decomposition : The opposite of Sythesis, which breaks down compounds.
AB= A+B

3)Single Replacement: When an element switches with another element in the equation, similar to this:
A+ BC=B+AC

4)Double Replacement: When both elements switch... like this
AB+CD=AD+BC

5) Neutralization : A reaction between an acid and a base, to form a compound and HOH
ACID+BASE= COMPOUND + HOH

6)Combustion: A reaction usually dealing with a hydrocarbon, that ALWAYS produces CO2 and HOH
Hydrocarbon + Oxygen = CO2 + HOH

There we have it, introduction to the world of Stoichiometry! Tune in next time for more!
