Consider the following unbalanced equation.?

Question

Mg(s) + H1+(aq) Mg2+(aq) + H2(g)
(a) Select all that apply.
H1+ is the substance being oxidized.
Mg is the reducing agent.
H1+ is the substance being reduced.
Mg is the substance being reduced.
H1+ is the reducing agent.
Mg is the substance being oxidized.
H1+ is the oxidzing agent.
Mg is the oxidzing agent.


Type the following answers using the formats given. Use only the format '1+' or '1-' for the charge on an ion. If only one electron is present in the half-cell reaction, type the answer as e- instead of 1e-.

Half-cell Equation Au3+(aq) + 3 e- Au(s)
Typed Answer Au3+(aq) + 3e- > Au(s)

--------------------------------------------------------------------------------

Balanced Equation 2 Au3+(aq) + 3 Zn(s) 2 Au(s) + 3 Zn2+(aq)
Typed Answer 2Au3+(aq) + 3Zn(s) > 2Au(s) + 3Zn2+(aq)

(b) Write the half-cell reaction for the oxidation.

(c) Write the half-cell reaction for the reduction.

(d) Write the balanced equation for the cell reaction. Keep substances in the order given in the original equation.

Answer 1

Mg is the reducing agent.
H1+ is the substance being reduced.
Mg is the substance being oxidized.
H1+ is the oxidzing agent.

b) Zn -> Zn2+ + 2e-
c) Au3+ + 3e- -> Au
