Chemical Reactions, Balancing Equations, and Formula Naming

Front

What is a chemical reaction?

Back

A process in which substances (reactants) undergo a transformation to form new substances (products).

Front

What does it mean to balance a chemical equation?

Back

To ensure that the number of atoms of each element is the same on both sides of the equation, adhering to the law of conservation of mass.

Front

What is the general form of a decomposition reaction?

Back

A reaction where one reactant breaks down into two or more products, represented as: A → B + C.

Front

What is a synthesis reaction?

Back

A reaction where two or more reactants combine to form a single product, represented as: A + B → C.

Front

What is a combustion reaction?

Back

A reaction that involves the burning of a substance in the presence of oxygen, typically producing carbon dioxide and water.

Front

What is the law of conservation of mass?

Back

In a chemical reaction, mass is neither created nor destroyed; the total mass of reactants equals the total mass of products.

Front

How do you identify a single replacement reaction?

Back

A reaction where one element replaces another in a compound, represented as: A + BC → AC + B.

Front

What is a double replacement reaction?

Back

A reaction where two compounds exchange ions or bonds to form two new compounds, represented as: AB + CD → AD + CB.

Front

What is the coefficient in a chemical equation?

Back

A number placed in front of a compound in a chemical equation to indicate the number of molecules or moles of that compound.
