... 1 in front of it to remind us we have done examining C4H10. Now the equation is updated to be 1 C4H10 + __ O2 __ CO2 + __ H2O Since C4H10 contains 4 carbon atoms, so we need four carbon atoms at the right side, which leads us to put 4 (called coefficient) in front of the CO2. Now the equation is u ...
