What is the law of conservation of mass?

Back

In a chemical reaction, mass is neither created nor destroyed; it remains constant.

Front

What is a balanced chemical equation?

Back

An equation where the number of atoms for each element is the same on both sides of the equation.

Front

What is a synthesis reaction?

Back

A type of reaction where two or more reactants combine to form a single product (A + B → AB).

Front

What is a decomposition reaction?

Back

A reaction where a single compound breaks down into two or more simpler products (AB → A + B).

Front

What is a single displacement reaction?

Back

A reaction where one element replaces another in a compound (A + BC → AC + B).

Front

What is a double displacement reaction?

Back

A reaction where two compounds exchange ions to form two new compounds (AB + CD → AD + CB).

Front

What is combustion?

Back

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

Front

How do you balance a chemical equation?

Back

Adjust the coefficients of the reactants and products to ensure the same number of each type of atom on both sides.

What is the difference between a liquid state and an aqueous state?

Back

Aqueous means a substance is dissolved in water, while liquid refers to the state of matter.
