Potassium nitrate does not have a net ionic equation. It is because potassium nitrate is not soluble and does not produce precipitates. The net ionic reaction is going to be Zn2+ + S2- -> ZnS(s). Zinc sulfide precipitates in the net ionic reaction.
If its oxidised, water and carbon dioxide is formed.
Answer: a disturbance that transfers energy.
Explanation:
By studying the fossil record we can tell how long life has existed on Earth, and how different plants and animals are related to each other. Often we can work out how and where they lived, and use this information to find out about ancient environments. Fossils can tell us a lot about the past.
As there is the increase in Oxidation number from +1 to +2. Hence, the correct Option (A) i.e, 1 to +2,
<h3>
What is Oxidation ?</h3>
Oxidation doesn't necessarily have anything to do with oxygen.
- Oxidation occurs when an atom, molecule, or ion loses one or more electrons in a chemical reaction.
- When oxidation occurs, the oxidation state or oxidation number of the chemical species increases.
- Oxidation doesn't necessarily involve oxygen! Originally, the term was used when oxygen caused electron loss in a reaction.
Hence, Option (A) indicates the oxidation as there is the increase in Oxidation number from +1 to +2.
