not understanding how these are wrong

Answer 1

Answer:

(1) Given equation is

Rb(s) + H2O(l) ------> RbOH(aq) + H2(g)

The balanced chemical equation is

2Rb(s) + 2H2O(l) ------> 2RbOH(aq) + H2(g)

Part C:

Given equation is

NiS(s) + O2(g) -------> NiO(s) + SO2(g)

The balanced chemical equation is

2NiS(s) + 3O2(g) -------> 2NiO(s) + 2SO2(g)

Part D:

Given equation is

PbO(s) + 2NH3(g) -------> Pb(s) + N2(g) + H2O(l)

The balanced chemical equation is

3PbO(s) + 2NH3(g) -------> 3Pb(s) + N2(g) + 3H2O(l)

Please let me know if you have any doubt. Thanks.
