Synthesis / Combustion / Single Replacement / Double Replacement (most Acid-Base Rxn) / Decomposition
Compounds combining to form
one product / O2 one of the reactants / One element reacting with a compound / Two compounds reacting / One reactant breaking into two or name.
X + Y → XY / X + O2 = XO2 / X + AB → XB + A / XY + AB → XB + AY / XY → X + Y
Trends
(1) Metal Oxide +H2O → Base
(Basic Anhydride)
Ex. Al2O3 (s) + 3H2O(l) → 2Al(OH)3 (aq)
(2) Nonmetal Oxide + H2O → Acid
(Acidic Anhydride)
Ex. N2O5 + H2O → 2HNO3
(3) Metal Oxide + Nonmetal Oxide → Salt
Ex. BaO(s) + N2O5 (s) → Ba(NO3)2 (s)
(4) Element + Element → Compound
Ex. C + S2 → CS2
Practice: P2O5 + H2O → ______/ (1) Metal + O2 → Metal Oxide
Ex. C(s) + O2 (g) → CO2(g)
(2) Hydrocarbon
Ex. CH4 (g) + O2 (g) → CO2 (g) + H2O(g)
Practice: C2H6 + O2 → ______/ (1) Activity Series
Ex. Metals
3K (s) + AlCl3 (aq) → 3KCl(aq) + Al(s)
(2) Nonmetals
Ex. 2NaBr (aq) + Cl2 (aq) → 2NaCl(aq) + Br2 (l)
Practice: Ca + H2O → ______
Zn + HCl→ ______/ (1) Acid Base
Ex. HF + NaOH → NaF+ H2O
(2) Hydrides + H2O → Hydroxide + H2
Ex. LiH(s) + H2O(l) → LiOH(aq) + H2 (g)
Practice: NaOH + H3PO4 → ______/ (1) Carbonate → CO2 + compound
Ex. CaCO3(s) → CaO(s) + CO2 (g)
(2) Chlorate → O2 + compound
Ex. 2KClO3 (s) → 2 KCl(s) + 3 O2 (g)
(3) Ammonium Carbonate → NH3 + CO2 + H2O
Ex. (NH4)2CO3 (s) → 2 NH3 (s) + CO2(g) + H2O (g)
(4) Bicarbonate → carbonate + H2O + CO2
Ex. 2NaHCO3 (s) → Na2CO3(s) + H2O(g)+ CO2(g)
(5) Hydrogen Peroxide → water + O2
Ex. 2H2O2 (l) → H2O(l) + O2 (g)
Special Cases:
H2CO3 → H2O + CO2
NH4OH → NH3 + H2O
H2SO3→ H2O + SO2
