BALANCING EQUATIONS ­ THE CGPWNED CRASH COURSE!
How do you balance equations? Student Answer: I don't know. Dude, its not an exam question.

Anyways in this section I shall try to explain how to balance equations!

INTRODUCING CHARGES

Ions are atoms that carry either a positive or negative charge. Compounds…

BALANCING A COMPOUND

If Chlorine is Cl2, then why is sodium chloride NaCl? Why not NaCl2? Well here's the thing.
Before even trying to balance an equation, you need to learn to balance a compound. But how
do you do it? Simple. We now know the charges (or at least…

Get it now? NO? okay I give up. If you do, then move on...




BALANCING EQUATIONS

Now it's the fun part! No...

Look at this:

2Na + Cl2 -> 2NaCl

Now let me remind you that on its own, any diatomic molecule must be written as element2.
However this also…

2Na + Cl2 -> 2NaCl
2 sodiums (total charge of 4+) + chlorine (total charge of 4- because of the diatomic molecule
thing) -> 2 sodium chlorides

Get it? At least understand it abit more? Okay let's try writing our own one! Lets write the
reaction between potassium and water.…

We know that Cl2 has to have that `2' because it is a diatomic particle and starts off by itself.
We also know this means Cl2 starts off with a charge of 2 x (1-), or a total of 2- charge. Lithium
only has a charge of 1+.

Lets use…
