Good day in this question we will be writing a balanced equation for the combustion of isoctane.
00:06
So combustion is a reaction between hydrocarbons, which in this case is c8h18, plus into the air, o2, that will yield carbon dioxide and h2o.
00:22
Balancing the equation, that is, balancing the equation is necessary because it will give us the relationship between between the reactors and the products and balancing the equation is a trial and error process.
00:36
So let us start balancing the carbon.
00:39
So since we have 8 here, let us try putting 8 also here.
00:44
Age is 18, so we need to put 9 here, so 9 times 2 is 18.
00:49
And then our 0 is 9 plus 8 times to 16, so 25.
00:57
We have 2 here, so we need to put 12 .5 here in order to have this in 25 but we need it in whole number so let us try putting 2 in the carbon so we will now have 16 also here and then 18 we have 18 h and 18 plus 16 times to 32 is 50 therefore we can now have we will now have 25 -0.

So let us check...
