Chemical Reactions and Balancing Equations

Front

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 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

What are reactants in a chemical equation?

Back

Substances that undergo a chemical change during a reaction, found on the left side of a chemical equation.

Front

What are products in a chemical equation?

Back

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

Front

What is a balanced chemical equation?

Back

An equation where the number of atoms for each element is the same on both sides, adhering to the law of conservation of mass.

Front

What is a decomposition reaction?

Back

A type of chemical reaction where one compound breaks down into two or more simpler products (e.g., ABC → A + B + C).

Front

What is an exothermic reaction?

Back

A reaction that releases energy, usually in the form of heat, to the surroundings.

Front

What is an endothermic reaction?

Back

A reaction that absorbs energy from the surroundings, resulting in a decrease in temperature.

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.

Front

What is a synthesis reaction?

Back

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