Identify each of the following reactions as a synthesis, decomposition, single displacement, or double displacement reaction. 1. N2(g) + 3H2(g) → 2NH3(g)

2. 2Al(s) + 3CuO(s) → Al2O3(s) + 3Cu(s)
3. CaCO3(s) → CaO(s) + CO2(g)
4. 2Li(s) + Br2(g) → 2LiBr(s)
5. 3Sn(NO3)4(aq) + 4K3PO4(aq) → 12KNO3(aq) +Sn3(PO4)4(s)

6. Mg(s) + 2HCl(aq) → MgCl2(aq) + H2(g)
7. Copper displaces silver in aqueous silver nitrate in a single displacement reaction as follows.
Cu(s) + 2AgNO3(aq) → 2Ag(s) + Cu(NO3)2(aq)
a) If zinc replaces copper, will a single displacement reaction still occur?
b) If a single displacement reaction occurs, predict the products of the reaction.
