Unit 3 IPC Chemical Reactions

Front

What is the law of conservation of mass?

Back

The law of conservation of mass states that in a chemical reaction, the total mass of the reactants equals the total mass of the products.

Front

What is a chemical reaction?

Back

A chemical reaction is a process that involves the transformation of one or more substances into different substances.

Front

What are reactants in a chemical equation?

Back

Reactants are the starting materials 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 is a coefficient in a chemical equation?

Back

A coefficient is a number placed in front of a chemical formula to indicate how many molecules or moles of that substance are involved in the reaction.

Front

What is a subscript in a chemical formula?

Back

A subscript is a small number written after an element symbol that indicates the number of atoms of that element in a molecule.

Front

What is an ionic bond?

Back

An ionic bond is a type of chemical bond formed between a metal and a non-metal, where electrons are transferred from one atom to another.

Front

What is an exothermic reaction?

Back

An exothermic reaction is a chemical reaction that releases energy in the form of heat or light.

Front

What is an endothermic reaction?

Back

An endothermic reaction is a chemical reaction that absorbs energy from its surroundings.

Front

What is a balanced chemical equation?

Back

A balanced chemical equation has the same number of each type of atom on both sides of the equation, reflecting the law of conservation of mass.
