So what is meant by a balanced equation? i think the best way to answer this question is just giving an example.
00:07
So let's say we have c4h10 and we're combusting it with oxygen, right? products, we know it's co2, co2 plus h2.
00:31
So to balance this, we need 10 hydrogens on the right, so 10 hydrogens on, sorry, hydrogens on the left, so 10 hydrogers on the right, and four carbons on the left, four carbons on the right.
00:49
And so since there are eight oxygens on the right, and eight plus five on the right, so 13, so 13 and a half.
01:00
So if you check each atom on the left versus right sides, you will find that they are exactly equal.
01:07
And we could rewrite this equation by simply doubling, one second, simply by doubling both sides so that we won't have a fraction as a coefficient.

C4h10 plus 13 of 2 yields 5h2 plus 8 co2.

Let's just make sure that there are enough...
