Identify the type of chemical reaction. Ex. ZnCl2(aq) + Mg(s) → Zn(s) + MgCl2(aq) --> Single replacement

2KOH(aq) + CuSO4(aq) → Cu(OH)2(s) + K2SO4(aq) --> ?
2Al(s) + 3Br2(l) → 2AlBr3(s) --> ?
4PBr3(l) → P4(s) + 6Br2(l) --> ?
2C2H6(g) + 7O2(g) → 4CO2(g) + 6H2O(g) --> ?

Does it occur? Single Replacement Reactions
Ex. NO Ag(s) + KNO3(aq) → AgNO3 (aq) + K(s)

? Zn(s) + 2AgNO3(aq) → Zn(NO3)2 (aq) + 2Ag(s)

? Mg(s) + CdO(aq) → MgO(aq) + Cd(s)

? 2Al(s) + 3BaCl2(aq) → 2AlCl3 (aq) + 3Ba(s)
