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

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

Li2CO3 → LiO + CO2
Li 2 CO 3 → LiO + CO 2

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

CO2 + H2O → CH2OH + O2

Answer 1

Zn + 2HCl → H2 + ZnCl2

Answer 2

Yes, Zn + 2HCl → H2 + ZnCl2

The wording of the question is nutty though. The other options are not balanced reactions so they are just plain not reactions.

Answer 3

I apologize for the confusion in the wording of the question. Thank you for pointing that out. The balanced equation Zn + 2HCl → H2 + ZnCl2 is the only one where the number of atoms in the reactants is the same as the number of atoms in the products.
