Types of Chemical Reactions Review

Front

What type of reaction is represented by the equation: 2NO₂ → N₂ + 2O₂?

Back

Decomposition reaction: A reaction where a single compound breaks down into two or more simpler products.

What type of reaction is represented by the equation: 3KOH + H₃PO₄ → K₃PO₄ + 3H₂O?

Back

Double displacement reaction: A reaction where two compounds exchange ions to form two new compounds.

Front

What are the substances at the beginning of a chemical equation called?

Back

Reactants: The starting materials in a chemical reaction.

Front

What type of reaction is represented by the equation: PbCl₂ + AgNO₃ → Pb(NO₃)₂ + AgCl?

Back

Double replacement reaction: A reaction where the anions and cations of two different compounds switch places.

Front

What type of reaction is represented by the equation: C₅H₁₀O₄ + O₂ → CO₂ + H₂O?

Back

Combustion reaction: A reaction where a substance combines with oxygen, releasing energy in the form of light or heat.

Front

Define a synthesis reaction.

Back

Synthesis reaction: A reaction where two or more reactants combine to form a single product.

Front

What is a single displacement reaction?

Back

Single displacement reaction: A reaction where one element replaces another element in a compound.

Front

What is the general form of a combustion reaction?

Back

Combustion reactions typically involve a hydrocarbon reacting with oxygen to produce carbon dioxide and water.

Front

What is the difference between a physical change and a chemical change?

Back

A physical change alters the form of a substance but not its chemical composition, while a chemical change results in the formation of new substances.

Front

What is the law of conservation of mass?

Back

The law of conservation of mass states that mass is neither created nor destroyed in a chemical reaction.
