Law of Conservation of MassAKA: Law of Conservation of Matter

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.
