Front

What are reactants in a chemical reaction?

Back

The starting substances that undergo change during a chemical reaction.

Front

What are products in a chemical reaction?

Back

The substances that are formed as a result of a chemical reaction.

Front

What is a synthesis reaction?

Back

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

Front

What is a decomposition reaction?

Back

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

Front

What is a single displacement reaction?

Back

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

Front

What is a double displacement reaction?

Back

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

What is an example of a synthesis reaction?

Back

2 H₂ + O₂ → 2 H₂O (Hydrogen and oxygen combine to form water.)

Front

What is an example of a decomposition reaction?

Back

2 H₂O → 2 H₂ + O₂ (Water decomposes into hydrogen and oxygen.)

Front

What is an example of a single displacement reaction?

Back

Zn + 2 HCl → ZnCl₂ + H₂ (Zinc displaces hydrogen in hydrochloric acid.)
