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

c o sub 2 plus h sub 2 o rightarrow c cap h sub 2 o h plus o sub 2

Zn+2HCl→H2+ZnCl2

z n plus 2 h c l rightarrow h sub 2 plus z n c l sub 2

Li2CO3→LiO+CO2

l i sub 2 c o sub 3 rightarrow l i o plus c o sub 2

CH4+O2→CO2+2H2O

c h sub 4 plus o sub 2 rightarrow c o sub 2 plus 2 h sub 2 o

Answer 1

Zn + 2HCl → H2 + ZnCl2

Count atoms:
- Reactants: Zn 1, H 2, Cl 2
- Products: Zn 1, H 2, Cl 2

All elements have the same number of atoms on both sides.
