Types of chemical reactions (23-24)

Front

What are the reactants in a chemical equation?

Back

The reactants are the substances that undergo a chemical change, found on the left side of a chemical equation.

Front

What is evidence of a chemical reaction?

Back

Evidence of a chemical reaction includes gas (bubbles) formation, color change, temperature change, and the formation of a precipitate.

Front

What type of chemical reaction is represented by the equation C2H2 + O2 --> CO2 + H2O?

Back

This is a combustion reaction, where a hydrocarbon reacts with oxygen to produce carbon dioxide and water.

Front

What is a decomposition reaction?

Back

A decomposition reaction is a type of chemical reaction where a single compound breaks down into two or more simpler substances.

Front

What are the products of the combustion of methane (CH4)?

Back

The products of the combustion of methane are carbon dioxide (CO2) and water (H2O).

Front

What is a synthesis reaction?

Back

A synthesis reaction is a type of chemical reaction where two or more reactants combine to form a single product.

Front

What is a single displacement reaction?

Back

A single displacement reaction is a type of chemical reaction where one element replaces another element in a compound.

Front

What is a double displacement reaction?

Back

A double displacement reaction is a type of chemical reaction where two compounds exchange ions or bonds to form two new compounds.

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; the total mass of reactants equals the total mass of products.

Front

What is an exothermic reaction?

Back

An exothermic reaction is a chemical reaction that releases energy in the form of heat or light.
