Explain what "LEO the lion goes GER" means based upon what you have learned
olchik [2.2K]

"LEO the lion goes GER" means based upon the oxidation and reduction reactions.

<h3>What is oxidation and reduction reaction?</h3>

Oxidation reactions are those reactions in which lossing of electrons are taking place from the substrate molecule and in reduction process gaining of electrons is done by substrate molecules.

The phrase "LEO the lion goes GER" is used in the context of oxidation and reduction reactions. Meaning of the terms:
LEO → Lose electrons = oxidation

GER → Gain electrons = reduction

Hence the given line is based on oxidation and reduction.

What are the correct half reactions for the following reaction:<br> Zn + 2 HCI -&gt; H₂ +zncl2
Ipatiy [6.2K]

Answer:

Zn(s) + 2H+(aq) => Zn²+(aq) + H2 (g)

Explanation:

The equation Zn + 2 HCI -> H₂ +zncl2 on reduction and oxidation, it results as below;

  • 2H+ + 2e- => H2 ; reduction
  • Zn => Zn²+ + 2e- ; oxidation

The equations above are half cell.

On combination of the above half cell reaction equations gives;

Zn(s) + 2H+(aq) => Zn²+(aq) + H2 (g).

Therefore, the half reaction equation for Zn + 2 HCI -> H₂ +zncl2 is given by;

Zn(s) + 2H+(aq) => Zn²+(aq) + H2 (g).
