CH4 + O2 → CO2 + 2H2O
CH 4 + O 2 → CO 2 + 2H 2 O
Zn + 2HCl → H2 + ZnCl2
Zn + 2HCl → H 2 + ZnCl 2
Li2CO3 → LiO + CO2
Li 2 CO 3 → LiO + CO 2
CO2 + H2O → CH2OH + O2
The chemical equation in which the number of atoms in the reactants is the same as the number of atoms in the products is:
Zn + 2HCl → H2 + ZnCl2
