4.2 Net Ionic Equations + 4.3 Representations of Reactions

What can represent all physical and chemical processes?

Balanced equations

What do chemical equations represent?

Chemical changes

What are chemical changes the result of?

Rearrangement of atoms into new combinations

What do equations demonstrate?

Mass is conserved in chemical reactions

How do equations demonstrate that mass is conserved in chemical reactions?

By containing equal numbers of atoms of every element before and after the change occurred

What does the fact that chemical changes are the result of rearrangement of atoms into new combinations mean for chemical equations?

There should be equal numbers of atoms of every element before and after the chemical change

Differing forms used to represent a chemical reaction:

Balanced molecular, complete ionic, and net ionic

What does the form used to represent a chemical reaction depend on?

The context in which it is to be used

What can balanced chemical equations in their various forms be translated into?

Symbolic particulate representations
