Write the balanced chemical equation for each reaction. b. Cobalt(III) oxide reacts with hydrogen gas to form solid cobalt and liquid water.
Co2O3(s) + 3 H2(g) → 2 Co(s) + 2 H2O(l)
Co3O2(s) + 2 H2(g) → 3 Co(s) + 2 H2O(l)
Co2O3(s) + 3 H2(g) → 2 Co(s) + 3 H2O(l)
Co3O2(s) + 3 H2(g) → 2 Co(s) + 3 H2O(l)
