1) NaCl(aq) + AgNO3(aq) → double displacement
2) Fe + CuSO4 (aq) → FeSO4 (aq) + Cu (s) The type of reaction is a displacement reaction.
3) C4H 10(g) +O2(g) → 4CO2(g) +5H 2O(g) - combustion reaction
4)Ba (NO3)2 + Na2SO4 → BaSO4 + 2NaNO3 -double replacement reaction
5) AgNO3 + Li = LiNO3 + Ag might be an ionic equation.- redox reaction
6) LiBr(aq) + Cu(s) = CuBr(s) + Li(s)- redox reaction (ionic equation)
