Law of Conservation of Mass AKA: 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.

Mass of Reactants = Mass of Products Reactants Products Mass 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.
