What is a chemical reaction?

Back

A process in which substances (reactants) are transformed into different substances (products) through the breaking and forming of chemical bonds.

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 balanced chemical equation?

Back

An equation that has the same number of each type of atom on both sides, indicating that mass is conserved.

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 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 or bonds to form two new compounds.

Front

What is a combustion reaction?

Back

A reaction that occurs when a substance combines with oxygen, releasing energy in the form of light and heat, typically producing CO2 and H2O.

Front

What is an activity series?

Back

A list of metals arranged in order of decreasing reactivity, used to predict the outcomes of single replacement reactions.

Front

How do you determine the products of a reaction?

Back

By using the reactivity of the elements involved, the type of reaction, and balancing the equation.
