Question

In which chemical equation is the number of atoms in the reactants the same as the number of atoms in the products?(1 point)
Responses

CO2 + H2O → CH2OH + O2
CO 2 + H 2 O → CH 2 OH + O 2

Zn + 2HCl → H2 + ZnCl2
Zn + 2HCl → H 2 + ZnCl 2

CH4 + O2 → CO2 + 2H2O
CH 4 + O 2 → CO 2 + 2H 2 O

Li2CO3 → LiO + CO2
