Explanation:
Ammonium Fluoride and Potassium Sulphate
The following statements from the paragraph are true. Protons have a mass that contributes significantly to the mass of the atomic nucleus. Neutrons have a mass that contributes significantly to the mass of the atomic nucleus. Electrons have a very low mass and are not found in the nucleus but instead are found in surrounding orbits.
Electrons because electrons are found in the electron cloud outside the nucleus.
Answer:
Equation 1 - nuclear fission
Equation 2 - nuclear fusion
Explanation:
Nuclear fission is a reaction in which a large nucleus is split into smaller nuclei when it is bombarded by neutrons. The process produces more neutrons to continue the chain reaction. This is clearly depicted in equation 1 as shown in the question.
Nuclear fusion is a reaction in which two light nuclei combine in order to form a larger nuclei. This is clearly depicted in equation 2 as shown in the question.
Answer:
The systematic naming of chemicals is the IUPAC name (International Union of Pure and Applied Chemistry).
Here are the purposes to use it:
1/ It identifies exactly one chemical.
2/ All people over the world can understand it, wherever they are, whoever they are.
It looks like how we recognise the number 1 - 2 - 3: the Americans call them One Two Three, but the Russian call them Odin Dva Tri, etc....
