How do you balance C6H14 plus O2 - CO2 plus H₂O?

Answer 1

You just have to have the same number of each atom on each side of the equation so we put large numbers in front of each section of the formula

for C6H14 + O2 -> CO2 + H2O

we can see that on the left hand side of the formula there are 6 c's 14 h's and 2 o's whereas on the right there is 1 c, 3 o's and 2 h's and as we need equal numbers on both sides we add numbers INFRONT of the sections like this;

2C6H14 + 13O2 -> 12CO2 + 14H20
