Chemical Compounds and Formulas
"Compounds are two or more atoms bonded together"
Subscripts = how many atoms of the element there are
Changes in subscripts or element combinations = chemical reaction!
3
Chemical Reactions
"Any change that results in the breaking or formation of chemical bonds"
When compounds break down into pieces or pieces/atoms come together to form new compounds
4
The Law of Conservation of Mass
"Matter can be neither created nor destroyed"
Chemical reactions cannot result in a gain or loss of atoms
If an atom is on one side, it's got to be on the other side too
