REDOX Flashcards
1
Q
Assigning oxidation numbers
A
- Atoms in elemental state is 0 (Only 1 type of atom)
-Atoms in monoatomic ions is its charge
-Atoms in polyatomic ions same as if it were monoatomic (OH- = O is -2)
2
Q
H in equation
A
WILL ALWAYS BE H2 NOT JUST H
3
Q
Activity series top
A
-Neutral atoms at the top give up electrons easily
-Oxidized easily
4
Q
Activity series bottom
A
-Neutral atoms at the bottom don’t give up electrons easily
-But corresponding cations take e well
-Easily reduced
5
Q
Activity series reactions
A
-Only react if Neutral is higher than cation
6
Q
Activity series chart in class
A
It is upside down. The bottom neutral are the top of ox. If the neutral is closest to ox than cation its yes it reacts.
7
Q

A
Must be reactants
