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 Li2CO3 → LiO + CO2 Li 2 CO 3 → LiO + CO 2 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
Zn + 2HCl → H2 + ZnCl2
The chemical equation in which the number of atoms in the reactants is the same as the number of atoms in the products is:
CH4 + O2 → CO2 + 2H2O
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
To determine this, we need to count the number of atoms on both sides of the equation. In this equation, the reactants are Zn (1 atom) and 2HCl (1 atom of hydrogen and 1 atom of chlorine, totaling 2 atoms). On the product side, we have H2 (2 atoms of hydrogen) and ZnCl2 (1 atom of zinc and 2 atoms of chlorine, totaling 3 atoms).
So, both the reactants and products have a total of 3 atoms, making the equation balanced with an equal number of reactant and product atoms.
