To balance a reaction, we must say to it that the number of elements in one side is equal to the other side. For a combustion reaction such as the one given, we first need to balance the number of carbon atoms, then the hydrogen atoms and lastly the oxygen atoms.
<span>C4H10 + 13/2O2 → 4CO2 + 5H2O.</span>
As you said, the answer is 150.
But in all the numbers, there's a comma with two zeros, and so you have to put them in your answer : 150,00
They are the significative numbers.
Hope it helps
