Mass is neither created nor destroyed during a
chemical reaction

In a chemical reaction, atoms are rearranged to make new
products with new properties.

A chemical reaction is when chemical bonds break and new
bonds form.

Reactants ProductsMass of Reactants = Mass of Products

This is a balanced equation

Chemical reactions are represented on
paper by chemical equations.

Chemical equations are a shorter, easier way to show
chemical reactions because they use symbols
instead of words.

Coefficients show the number of each type of molecule in a reaction.
Subscripts show the number of each type of atom in a reaction.
