Answer 1

Solution:

9) Option B and C

The correct equation will be;

CuCl (s) + water = Cu+ (aq) + Cl- (aq)

Thus, the given equation contains incorrect charges and missing state of CuCl (s).

10) Option E

The given equation is correct,

Cu(OH)2 (s) + heat = CuO (s) + H2O (g)

11) Option A and D

The correct equation will be;

CuO (s) + H2SO4 (aq) = CuSO5 (aq) + H2 (g)

Thus, the given equation contains incorrect balancing and identity of H2SO5 (aq) is unclear.
