a) CaCI^2(aq)+NH^4OH(aq)---->Ca(OH)^2(s)+NH^4CI(aq)
b)Sc^2(CO^3)^3(s)--->Sc^2O^3(s)+CO^2(g)

CaCl2 + 2NH4OH ----> Ca(OH)2 + 2NH4Cl
Double replacement/ double decomposition (precipitation).
Sc2(CO3)3 -----> Sc2O3 + 3CO2
Thermal decomposition. Scandium carbonate doesn't actually exist, but let's not spoil a good question!

idk the reaction style yet i pass to stability those for u: a million. CuO + H2 = Cu + H2O 2. HCl + NaOH = H2O + NaCl 3. WO3 + 3 H2 = W + 3 H2O 4. Sn(cr) + 2 KOH(aq) = K2SnO2(cr) + H2 5. 3 SiF4(cr) + 3 H2O(l) = 2 H2SiF6(aq) + H2SiO3(cr) sorry i couldnt tell u what type, yet im extremely useful on my balancing. desire i helped.

a)CaCl^2+2NH4OH=Ca(OH)2+2NH4Cl
double decomposition/precipitation
b)I have no idea check under the reactions of Sc.
