Front

What happens to temperature in an exothermic reaction?

Back

Temperature increases outside of the reaction.

Front

What is a covalent bond?

Back

A bond formed by the sharing of electrons between two nonmetals.

Front

What is an ionic bond?

Back

A bond formed by the transfer of electrons from one atom to another, typically between a metal and a nonmetal.

Front

What is the difference between exothermic and endothermic reactions?

Back

Exothermic reactions release heat, while endothermic reactions absorb heat.

Front

What is a chemical equation?

Back

A symbolic representation of a chemical reaction showing the reactants and 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.
