For the reaction below, determine the stoichiometric coefficient
on the hydrogen ion in the balanced redox reaction in acid
solution. In compounds, the oxidation state of O is 2-. Assume X is
a diatomic element and that M is a metal that can have multiple
oxidation states. This question is not multiple choice, you will
input the integer answer to this question.

MO 4 3-(aq) + X (aq) →
X 2+(aq) + M +(aq)
6. For the reaction below, determine the stoichiometric
coefficient on OH - in the balanced redox
reaction in basic solution. In compounds, the oxidation state of O
is 2 -. Assume X is a nonmetal and that M is a
metal that can have multiple oxidation states. This question is not
multiple choice, you will input the integer answer to this
question.

MO 3 2- (aq) +
X 2- (aq) →
XO 2 - (aq) + MO (s)
7.
In the following electrochemical cell, which is the half
reaction at the anode?

Ni 2+ ( aq) + Cd
( s) → Ni ( s) +
Cd 2+ ( aq)

Standard Reduction Potentials
Ni 2+ ( aq) +
2 e - → Ni ( s)  
-0.26 V
Cd 2+ ( aq) +
2 e - → Cd ( s)  
-0.40 V
8. Calculate the standard cell potential for the following
electrochemical cell.

2 Ag + ( aq) + Cu
( s) → 2 Ag ( s) +
Cu 2+ ( aq)

Standard Reduction Potentials
Cu 2+ ( aq) +
2 e - → Cu ( s)  
0.337 V
Ag + ( aq)
+ e - → Ag ( s)  
0.7996 V
