VE Balancing Equations, Chemical Reactions,

Front

What is a balanced equation?

Back

A balanced equation has the same number of each type of atom on both sides of the equation, indicating that mass is conserved during the reaction.

Front

What is a chemical reaction?

Back

A process where substances (reactants) are transformed into new substances (products).

Front

What is the difference between an ionic bond and a covalent bond?

Back

Ionic bonds involve the transfer of electrons between metals and nonmetals, while covalent bonds involve the sharing of electrons between nonmetals.
