Starter Write the balanced formula equation for the

following reaction Identify the type of reaction Aqueous lead (II) nitrate was mixed with a

hydrochloric acid to create lead (II) chloride and nitric acid.

Ch. 8 Chemical Equations and

Reactions8.2b Predicting Products of

Chemical Reactions

Types of Reactions we are going to learn how to predict

products in simple reactions of each type will need to identify type for more complex

reactions but not predict products

1. Synthesis making binary compounds find ions created by each reactant Criss-cross to make product

1. Synthesis barium metal is reacted with solid sulfur.

magnesium metal reacts with bromine

2. Decomposition of binary compounds find elements that will be created write them in natural state

2. Decomposition Solid silver oxide is heated.

Water undergoes decomposition.

3. Single Replacement Identify the “similar” element in the

compound that it will replace Find ions created crossover to make new compound

3. Single Replacement zinc metal is added to solution of lead(II)

nitrate

sodium iodide is added to chlorine gas

4. Double Replacement identify which parts will switch places find ions that will be created crossover to create new compounds

4. Double Replacement silver nitrate and sodium chloride solutions

are mixed

solutions of magnesium fluoride and potassium hydroxide are mixed

5. Combustion Reaction of ANY element/compound with

O2

choose products based on what elements exist in reactants

5. Combustion Methane (CH4) burns in air.

Magnesium metal reacts with oxygen in the air.

Examples Identify the type of reaction Predict the products Write the chemical equation Balance the reaction

Hydrogen sulfide gas is bubbled through a solution of potassium hydroxide

Liquid butanol (C4H9OH) is burned in oxygen gas.

Liquid bromine is mixed with sodium iodide solution.

Calcium metal is heated strongly in nitrogen gas.

Liquid water is decomposed through electrolysis.
