Answer:
The process describes the source of energy of the Sun such that it shines as a result of nuclear fusion of hydrogen taking place.
Explanation:
The Sun generates energy by hydrogen within the Sun undergoing nuclear fusion to form helium.
Nuclear fusion reaction involves combining of two or more atomic nuclei to produce one or more completely different atomic nuclei as well as protons or neutrons, with a loss or gain of mass and the release or absorption of energy.
The process whereby four hydrogen atoms combine to form one helium atom with a mass deficit, which is accounted for by the release of energy, result in the high intense light of the Sun.
This set up of a conversion table should show you that if you multiply

Answer:
the physical and chemical properties of the products are different from the reactants
Explanation:
A chemical reaction involves the chemical combination of two or more elements/compounds called Reactants to give one or more different elements/compounds called Products. A chemical reaction occurs in such a way that the atoms of the reactants are restructured to form product(s) that is/are entirely different from the reactants.
In a chemical reaction, the physical and chemical properties of the products differ from that of the reactants since different chemical compounds/elements are formed as products. The physical properties of a substance, which include colour, melting and boiling point etc. will differ in the reactants and products formed. Also, the chemical structure and identity of the reactants will be changed to give rise to a different chemical property in the products.
Explanation:
If a large photon strikes the surface, that has enough strength to take out an electrode, which will then travel to the positive side since it is negative. Current is flowing at this stage. Since the reduced photons will be unable to distinguish between atoms, no power can pass.
Explanation:
Salts are the solutes in an aqueous solution. An aqueous solution is solution whose solvent water.
- To form a solution,a solute must be dissolved in a solvent.
- For aqueous solutions, the solvent which is the dissolving medium is made up of water.
- The solute is the substance that is dissolved in it.
- Salts for example can be a solute in an aqueous solution.
- A salt is generally an ionic compound consisting of positive ions such as metallic, ammonium ans complex ions and negative ions such as acid radicals and complex ions.
