Displacement reaction and redox Flashcards
1
Q
What is a Redox reaction?
A
A reaction when electrons are transferred between substances.
2
Q
What is Oxidation?
A
LOSS of electron
or
GAIN of OXYGEN (this is the miscellaneous one)
3
Q
What is REDUCTION?
A
GAIN of electron
or
LOSS of OXYGEN (This is miscellaneous one)
4
Q
OILRIG
A
OXIDATION is LOSS
REDUTION is GAIN
5
Q
What is displacement reaction?
A
A type of redox reaction
Where MORE reactive element reacts to take place of the LESS reactive element IN A COMPOUND
6
Q
How to form a ionic equation?
A
WRITE ELEMENTS THAT CHANGE:
Ca+Fe(+2) SO4(-2)==> Ca(+2) SO4 (-2) +Fe
so ionic equation is:
Ca+Fe +2 ==> Ca+2 + Fe
7
Q
How to form Half equation?
A
Ca ==> Ca (+2) + e-2
Fe(+2) + e-2 ==> Fe
