Question

In the reaction Zn + H+ ---> Zn2+ + H2, Zn is oxidized and H is reduced.

Answer 1

Answer:

2H⁺ + 2e → H₂.

Zn → Zn²⁺ + 2e.

Explanation:

• The reaction includes two half-reactions:

The reduction reaction:

2H⁺ + 2e → H₂.

• 2.0 moles of hydrogen ions is reduced by 2 electrons to produce 1.0 mole of hydrogen gas.

The oxidation reaction:

Zn → Zn²⁺ + 2e.

• 1.0 mole of Zn metal is oxidized to Zn²⁺ and releases 2 electrons.

• The overall reaction will be:

Zn + 2H⁺  → Zn²⁺ + H₂.

Answer 2

Answer:

How many electrons would be produced and used in the balanced half-reactions?  its 2

Explanation:

Complete the balanced half-reactions:

2 H⁺ + 2 e → 1 H₂.

1 Zn → 1 Zn²⁺ + 2 e.
