2K + 2H2O --> 2KOH + H2
The balanced equation shows that there is a 2 in front of water.
The fully balanced out equation for Water is:
2H2 + O2 = 2H2O
2
The balanced equation is 3 Fe3O4 + 8 Al -> 4 Al2O3 + 9 Fe. Therefore, the coefficient of Fe is 9.
2H2O2------------ 2 H2O + O2 thus correct coefficient is 2
The coefficient of O2 is 5.The chemical equation is:C5H12 + 8 O2 = 5 CO2 + 6 H2O

2NF3 --> N2 + 3F2
2NF3 --> N2 + 3F2
The balanced equation is 3 Fe3O4 + 8 Al -> 4 Al2O3 + 9 Fe. Therefore, the coefficient of Fe is 9.
2H2O2------------ 2 H2O + O2 thus correct coefficient is 2
2
The coefficient of O2 is 5.The chemical equation is:C5H12 + 8 O2 = 5 CO2 + 6 H2O
2
the answer is 2 apex
The chemical equation is:C5H12 + 8 O2 = 5 CO2 + 6 H2O
The chemical equation is:C5H12 + 8 O2 = 5 CO2 + 6 H2O
Cu + 2H2SO4 ==> CuSO4 + SO2 + 2H2OSo coefficient of CuSO4 is 1
