A substance that has mass and occupies volume with characteristic properties. 

Law of Conservation of Matter 

The total amount of materials present before a chemical reaction is the same as that present at the end of it. “Matter can neither be created nor destroyed in a chemical reaction.” 

Law of Conservation of Energy 

The total energy of a system before a chemical reaction is the same as the total energy at the end of the reaction. It can transform but cannot disappear. “Energy can neither be created nor destroyed.” 

Characteristic Properties of Matter 

mass, volume, density, temperature, reactivity, conductivity, color, etc.

When adding and subtracting, how are the significant figures determined? 

You ignore the places to the left of the decimal place. You then count the decimal places to the right of the decimal place and then take the smallest number. This is the number of significant figures behind the decimal. 

When multiplying and dividing, how are the significant figures determined? 

You count the sig figs in all the numbers and choose the least number.
