Below are sample questions representative of the exercises included on this worksheet and related 9.37 Types of Chemical Reactions skill assessments:

Problem 1Difficulty: Mastery

Which classification best matches C2H5OH + 3O2 -> 2CO2 + 3H2O while preserving the reaction pattern?

ACombustion; ethanol reacts with oxygen and forms CO2 and H2O.

BSynthesis; all reactants combine into carbon dioxide only.

CAcid-base; ethanol neutralizes oxygen to make water.

DDouble replacement; carbon and hydrogen trade partners with oxygen.

Solution & Explanation:Ethanol is a carbon-containing fuel. With O2 as a reactant and CO2 and H2O as products, the reaction is combustion.

Problem 2Difficulty: Mastery

Classify this equation: NH4NO3 -> N2O + 2H2O.

ADouble replacement; two compounds exchange ions.

BSynthesis; nitrogen and water combine into ammonium nitrate.

CDecomposition; one compound forms nitrous oxide and water.

DSingle replacement; nitrogen replaces hydrogen in a compound.

Solution & Explanation:Ammonium nitrate is the only reactant and it forms multiple products, which is decomposition.

Problem 3Difficulty: Mastery

Classify this equation: Li2O + CO2 -> Li2CO3.

ACombustion; carbon dioxide reacts as a fuel product.

BSynthesis; two compounds combine to form one product.

CDecomposition; lithium carbonate splits into two substances.

DDouble replacement; ions from two compounds exchange partners.

Solution & Explanation:The reactants combine into a single compound, lithium carbonate, so the reaction is synthesis.
