A. The atom has 3 protons, 3 electrons, and 4 neutrons.
"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.

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).
Solution. because the substances can't go back to their original form. like kool aid, when its mixed you cant separate the powder and the water again.
Like carbon-12 (C-12) and carbon-14 (C-14). C-12 is not radioactive but C-14 is radioactive. C-14 is radioactive isotope of C-12.
