Explanation:
Valence electrons are not related in anyways to nuclear reactions.
They do not take part in nuclear reactions. Only some inner orbital electrons have the tendency of taking part in nuclear reactions.
The valence electrons are the outermost electrons in an atom.
Nuclear reactions takes place in the nucleus of an atom.
Valence electrons are exchanged and shared for chemical reactions to take place in between atoms.
We can conclude that valence electrons have no relevance in nuclear reactions

First, you have to know the chemical formula of ozone and oxygen gas. Oxygen gas is O₂; it is one of the few gases that are diatomic in nature. The chemical formula of ozone is O₃. In oxygen gas, there are 2 particles of the oxygen element, while there are 3 particles for the ozone. There might be a slight difference but this induces a great difference in their properties. Oxygen is essential to living things because this is the gas that we breathe in. However, ozone is not safe to breathe in. It is a very strong oxidizing agent, almost 4 times as strong as the oxygen. Its main function is to block the UV rays from entering the Earth's atmosphere which can be harmful to our health.
Having known their chemical formula and properties, we know that an oxygen gas has 2 particles of oxygen element. So, if there are 24 particles of oxygen gas, that would mean 48 particles of the oxygen element. Since an ozone compound contains 3 particles of the oxygen element, then 48/3 = 16. It would take 16 particles of ozone to form 24 particles of the oxygen gas.
The answer to this questions is letterB

Answer:
The more worn-out the rock is, the older it is
Explanation:
Hello,
The different layers a rock has could be useful to date it, as long as the deepest layers account for the oldest rocks because they haven been worn out due to erosion and others natural events. Thus, one can say that the more worn-out the rock is, the older it is when we want to analyze a new section of strata.
Best regards.
