What is a coefficient?

• A number only involved at the beginning of a chemical formula

• A number after the chemical formula that indicates the amount of molecules involved in a chemical reaction

• A number in front of a chemical formula that indicates the amount of molecules involved in a chemical reaction

• A number only at the end of a chemical formula

What is Decomposition?

• a chemical reaction that breaks down compounds into simpler products

• a chemical reaction that builds compounds into complex products

• a chemical reaction where a product creates another product

• a chemical reaction where a reactant creates another reactant

What is an electron cloud?

• the area in a nucleus that is composed of neutrons and protons

• the area around the nucleus of an atom where the atom's electrons are most likely to be found

• the area composed only of neutrons in an element

• the area around the nucleus of a molecule where the atom's electrons are most likely to be found

Endothermic is when:

• A chemical reaction in which heat energy is given off by breaking chemical bonds

• A chemical reaction

• A chemical reaction in which ultraviolet energy is given off by breaking chemical bonds

• A chemical reaction where heat energy is absorbed by forming chemical bonds
