<span>The mantle is more dense, so it can not B.
Not even A , because the crust sure does contain naturally occurring radioactive material. Heat is also not efficiently transferred to the surface--most ground is cool,
so correct option is none is above that is D
hope it helps</span>
The three situations in which ionic reactions go to completion is formation of a gas, a precipitate and a slightly ionized product.
<h3>What are ionic reactions?</h3>
It indicates the flow of electrons and, therefore, the bonds broken and formed in the course of the reaction. It is theoretical, it can be corroborated by experiments, but sometimes there is no consensus on the mechanism by which a certain reaction occurs.
Chemical reactions are the result of the transformation that occurs in substances, where atoms rearrange themselves, modifying their initial state. Thus, chemical compounds undergo changes generating new molecules. In turn, the atoms of the elements remain unchanged.

Number one is sex cells are created
Answer:
texture
Explanation:
Elements have been classified into three categories namely; metals, non-metals and metalloids. This classification was done based on certain characteristics or properties possessed by each element. Some of the characteristics used are: lustre, malleability, conductivity, melting point, boiling point etc.
- Metals are very good conductors of heat and electricity whereas metalloids and nonmetals are not.
- Metals and metalloids shine when polished i.e. they are lustrous, whereas nonmetals don't
- Metals are malleable i.e. can be beaten into sheets.
Texture is not a property used to classify metals and metalloids.
