#1
Front (Question)

An oxidation reaction involves

Back (Answer)

gaining oxygen and/or losing electrons

#2
Front (Question)

A reduction reaction involves

Back (Answer)

losing oxygen and/or gaining electrons

#3
Front (Question)

anagram for oxidation and reduction

Back (Answer)

OIL RIG (oxidation is loss reduction is gain)

#4
Front (Question)

Example of oxidation

Back (Answer)

2MGO + O2 ==> 2MGO

#5
Front (Question)

Example of reduction

Back (Answer)

Fe2O3 + 3CO ==> 2Fe + 3CO2

#6
Front (Question)

Redox reactions involve

Back (Answer)

a reduction and a oxidation reaction

#7
Front (Question)

Example of redox reaction

Back (Answer)

• CuO + Zn ==> ZnO + Cu • We can rewrite Cu2+ + O2- ==> Zn2+ + O2- + Cu • we can remove oxygen because they are spectator ions and don’t take part in the reaction • Cu2+ + Zn ==> Zn2+ + Cu • We can make two half equations • Cu2+ + 2e- ==> Cu and Zn ==> Zn2+ + 2e- • Zinc is reducing agent and copper is oxidising agent

#8
Front (Question)

Iron(II) oxide (FeO) and Iron(III) oxide (Fe2O3) are

Back (Answer)

oxidation states which Iron(II) oxide as oxidation state of 2+ and Iron(III) oxide as 3+
