Explanation:
A fusion reaction is a reaction in which two or more small nuclei combine together to form a larger nuclei.
As it is known that a nucleus contains protons and neutrons. So when nuclei of two atoms combine together then there will be repulsion between the protons due to the presence of like charges. As neutrons have no charge so there will be no attraction or repulsion between neutrons of two nuclei.
Thus, we can conclude that in a fusion reaction, a major problem related to causing the nuclei to fuse into a single nucleus is the repulsion of nuclei.
Burning fossil fuels emits a number of air pollutants that are harmful to both the environment and public health. Sulfur dioxide (SO2) emissions, primarily the result of burning coal, contribute to acid rain and the formation of harmful particulate matter.
However, the use of solar panels is environment friendly. Solar power is renewable at absolutely no cost to supply energy infinitely. Also, it is very low maintenance. Once installed, the solar power system can last twenty to thirty years.
Similarly wind (turbines) and water (hydroelectric power plants) are an endless source of energy without negatively affecting the environment.

Answer:
according to my reading
use own words
Explanation:
Salts are combinations of acids and bases. The cation comes from a base and the anion from an acid. Therefore, to make KNO3 we react KOH and HNO3. See how that is done? We write K and add OH to make KOH. We take NO3 and add H to make HNO3.
