Explanation:
Detailed explanation-1: -To balance the hydrogen atoms, put a 2 in front of H2O: CH4 + O2 CO2 + 2H2O. The oxygen atoms can be balanced by putting a 2 in front of the O2 on the left: CH4 + 2O2 CO2 + 2H2O. The equation is now balanced.
Detailed explanation-2: -Therefore, the balance chemical equation is: 6CO2+6H2O→C6H12O6+6O2.
Detailed explanation-3: -The combustion of acetylene, C2H2 C 2 H 2, is a spontaneous reaction given by the equation 2C2H2(g)+5O2(g)→4CO2(g)+2H2O(l) 2 C 2 H 2 ( g ) + 5 O 2 ( g ) → 4 C O 2 ( g ) + 2 H 2 O ( l ) .
