Front

What are reactants in a chemical equation?

Back

Reactants are the starting substances in a chemical reaction that undergo change.

Front

What are products in a chemical equation?

Back

Products are the substances formed as a result of a chemical reaction.

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 mass of reactants equals the mass of products.

Front

What is the significance of balancing chemical equations?

Back

Balancing chemical equations ensures that the same number of each type of atom appears on both sides of the equation, reflecting the conservation of mass.

Front

What is the general form of a combustion reaction?

Back

A combustion reaction typically involves a hydrocarbon reacting with oxygen to produce carbon dioxide and water.
