Front

What is a single replacement reaction?

Back

A reaction where one element replaces another in a compound, resulting in a new element and a new compound.

Front

What is a double replacement reaction?

Back

A reaction where two compounds exchange ions to form two new compounds.

Front

What is a synthesis reaction?

Back

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

Front

What is a decomposition reaction?

Back

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

Front

What is a combustion reaction?

Back

A reaction that involves the burning of a substance in the presence of oxygen, producing heat and light.

Front

Example of a single replacement reaction:

Back

Mg(s) + 2HCl(aq) → MgCl2(aq) + H2(g)

Front

Example of a double replacement reaction:

Back

H3PO4(aq) + Ca(OH)2(s) → Ca3(PO4)2(s) + 3H2O(l)

Front

Example of a synthesis reaction:

Back

2H2(g) + O2(g) → 2H2O(l)

Front

Example of a decomposition reaction:

Back

2H2O(l) → 2H2(g) + O2(g)

Front

Example of a combustion reaction:

Back

CH4(g) + 2O2(g) → CO2(g) + 2H2O(g) + heat
