The law of conservation of matter states that mass is never created or destroyed in a chemical or physical process.

So, for example, if you have like a block of ice that's turning into water, excuse the bad ice cube.
00:22
I'll just say, you know, the ice mold wasn't very good.
00:26
And here's the water.
00:27
If you have 1 .23 grams of ice, i don't know, fairly random, then you're going to have 1 .2, 3 grams of liquid water at the end because the mass is conserved.
00:41
Then you have the law of conservation of energy, which states that the overall energy at the beginning of a process is the same as at the end of a process.
00:52
It can only be, it can't be created or destroyed.
00:55
It can only be transferred between, forms.
00:59
So for example, if you have like a combustion reaction, like this is a hydrocarbon called methane if it reacts with oxygen to form carbon dioxide plus water.

And let's balance two and two...
