Reaction Steps Identify Reaction Predict Products States of Matter Balance Equation
Synthesis Reaction Two single-type elements and/or a metal produce one product A+B AB
Synthesis Reaction Example Calcium reacts with oxygen 2Ca (S) +O 2 (g) 2CaO (aq)
Decomposition Reaction One reactant breaks down into two single type elements and/or a metal AB A+B
Decomposition Reaction Example Silver Oxide Is Heated 2AgO (S) 2Ag (S) +O 2 (g)
Single Replacement Reaction An element and a compound on the reactant side-an element and a compound on the product side. The anion from the reactant side switches partners as it transitions to the product side A+BX AX+B
Single Replacement Example Iron reacts with Copper (II) Chloride Fe (S) +CuCl 2 (aq) FeCl 2 (aq) +Cu (S)
Double Replacement Reaction 2 compounds on the reactant side, 2 compounds on the product side, and 2 ions switch partners as they transition to the product side AY+BX AX+BY
Double Replacement Reaction Example Copper (II) Oxide reacts with Sulfuric Acid CuO (s) +H 2 SO 4 (aq) CuSO 4 (aq) +H 2 O (l)
Acid Base Reaction Looks very similar to Double Replacement Acid+Base Water+Salt
Acid Base Reaction Example 1Ca(OH) 2 +2HF 2H 2 O (l) +CaF 2 (S)
Combustion Reaction Complete Combustion Hydrocarbon+O 2 CO 2 +H 2 0 Incomplete Reaction Hydrocarbon+O 2 CO 2 +H 2 0
Complete and Incomplete Combustion Reaction Examples Complete Combustion Combustion of Mg metal 2Mg+O 2 2MgO+Heat Incomplete Combustion Reaction Methane + Oxygen Carbon Monoxide + Water 2CH 4 (g) +3O 2 (g) 2CO (g) +4H 2 O (l)
States of Matter Solid No particle movement Ex: Ice, Table, Pencil, Paper Liquid Some particle movement Ex: Water, Mercury Gas Major particle movement Ex: Carbon, Hydrogen, Oxygen Aqueous Ex: Kool Aid, Gatorade
