Chemistry Study

The study of chemistry involves the systematic naming of substances, particularly focusing on the formation of ionic and covalent compounds. Ionic compounds typically consist of metals and non-metals and sometimes require the use of Roman numerals to indicate the charge of metal ions.

Typical State of Matter

Types of Reactions

Total combustion
Double Displacement
Acid - Base

Ha+bOH = AB + H2O

ab + cd = ad + cb
Single Displacement
a + bc = b + ac
Check solubility table
Check reactivity table

Only higher reactivity can displace

Decomposition
ab + energy = a + b
Synthesis
a + b= ab

Balancing Reactions

Redox
Electrons should add up

Hydrogen first, oxygens last

Basic
Elements should add up
