5. 2Na(s) + 2H2O(l) → 2NaOH(aq) + H2
Single-Replacement Reactions
2Na(s) + 2H2O(l) → 2NaOH(aq) + H2
Na+
Na+

6. Double-Replacement Reactions

7. CH4(g) + 2O2(g) → CO2(g) + 2H2O(g)
Combustion Reactions
CH4(g) O2(g) → CO2(g) + 2H2O(g)

10. PREDICTING PRODUCTS Mn + O2 g LiI + Cl2 g Al + Pb(NO3)2g
Element + Element = SYNTHESIS
LiI + Cl2 g
Compound + Nonmetal = SINGLE REPLACEMENT
Al + Pb(NO3)2g
Metal + Compound = SINGLE REPLACEMENT
KCl + Ag(NO3)g
Compound + Compound = DOUBLE REPLACEMENT
NH4NO2g
Compound = DECOMPOSTION

11. Cl2 + MgBr2 = Al + FeO3 = ZnCl2 + Ag(NO3) = H2O2 Zn + HCl =
NaOH + H2(SO4) =
Na + H2
Cu + H(CH3COO) =
