What is a balanced chemical equation?

Back

A balanced chemical equation has equal numbers of each type of atom on both sides of the equation, representing the conservation of mass.

Front

Write the balanced chemical equation for the combustion of methanol (CH4O).

Back

2 CH4O + 3 O2 → 2 CO2 + 4 H2O

Front

What are the products of the decomposition of water (H2O)?

Back

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 decomposition reaction?

Back

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

Front

What is a combustion reaction?

Back

A combustion reaction is a chemical reaction that occurs when a substance reacts with oxygen, producing energy in the form of heat and light.

Front

What is a single replacement reaction?

Back

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