Which of the following reactions obeys the law of conservation of atoms? h2o → h2 + o2 cuso4 + zn → zncl2 + cu zn + hcl → zncl2 + h2 pbcl2 + al → alcl3 + pb zn + 2hcl → h2 + zncl2

Zn + 2HCl → H2 + ZnCl2 obeys the Law of Conservation of Atoms.

On each side of the arrow there are 1 Zn atom, 2 H atoms, and 2 Cl atoms.

Thus, all atoms are conserved.
