Identifying Chemical Reactions

Front

What is a Synthesis (Combination) Reaction?

Back

A chemical reaction where two or more reactants combine to form a single product. Example: @@ ext{Na} + ext{Br}_2 ightarrow ext{NaBr}@@.

Front

What is a Decomposition Reaction?

Back

A chemical reaction where a single compound breaks down into two or more simpler products. Example: @@ ext{2H}_2 ext{O} ightarrow 2 ext{H}_2 + ext{O}_2@@.

Front

What is a Single Replacement Reaction?

Back

A chemical reaction where one element replaces another in a compound. Example: @@ ext{Cl}_2 + ext{NaBr} ightarrow ext{NaCl} + ext{Br}_2@@.

Front

What is a Double Replacement Reaction?

Back

A chemical reaction where two compounds exchange ions or bonds to form two new compounds. Example: @@ ext{CuCl}_2 + ext{H}_2 ext{S} ightarrow ext{CuS} + ext{HCl}@@.

Front

What is a Combustion Reaction?

Back

A chemical reaction that occurs when a substance combines with oxygen, releasing energy in the form of light or heat. Example: @@ ext{CH}_4 + ext{O}_2 ightarrow ext{CO}_2 + ext{H}_2 ext{O}@@.

Front

What are reactants in a chemical reaction?

Back

Substances that undergo change during a chemical reaction. They are found on the left side of the equation.

Front

What are products in a chemical reaction?

Back

Substances that are formed as a result of a chemical reaction. They are found on the right side of the equation.

Front

What is the law of conservation of mass?

Back

In a chemical reaction, mass is neither created nor destroyed; it is conserved.

Front

What is an example of a Synthesis Reaction?

Back

@@ ext{A} + ext{B} ightarrow ext{AB}@@.

Front

What is an example of a Decomposition Reaction?

Back

@@ ext{AB} ightarrow ext{A} + ext{B}@@.
