Types of Chemical Reactions

Front

What is a synthesis reaction?

Back

A synthesis reaction, also known as a combination reaction, occurs when two or more reactants combine to form a single product.

Front

What is a decomposition reaction?

Back

A decomposition reaction occurs when a single compound breaks down into two or more simpler products.

Front

What is a single replacement reaction?

Back

A single replacement reaction occurs when one element replaces another element in a compound.

Front

What is a double replacement reaction?

Back

A double replacement reaction occurs when the ions of two compounds exchange places in an aqueous solution to form two new compounds.

Front

What are reactants in a chemical equation?

Back

Reactants are the starting substances in a chemical reaction, found on the left side of the equation.

Front

What are products in a chemical equation?

Back

Products are the substances formed as a result of a chemical reaction, found on the right side of the equation.

Front

What does the arrow in a chemical equation represent?

Back

The arrow in a chemical equation represents the direction of the reaction, indicating that reactants are transformed into products.

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 total mass of reactants equals the total mass of products.
