Answer: precipitate.
Explanation:
1) When the product of the reaction between the chemicals in the solution is insoluble, then it cannot remain in the solution and it will precipiate, forming a solid substance.
2) That happens, for example, when you have two solutions with different solutes, mix them together, the solutes can react chemically with each other, yielding a product that is insoluble.
3) A typical example of such kind of precipitation reactions is athe neutralization of an acid and a base.
Acid + Base = salt + water
If the salt is insoluble in water then it will form a a precipitate (solid), if the product is soluble in water then it remains as an aqueos ions in the solution.
The number of electrons in an atom of an element being always the same
as the number of protons in its nucleus is False.
<h3>What is an Electron?</h3>
This is a sub-atomic particle which is negatively charged and is usually
involved in chemical reactions.
Electropositive elements donates electrons while electronegative
elements accepts electrons during chemical reactions which is why the
number of proton and electron aren't always the same.

Atoms which might substitute for one another can be found in the same column in the periodic table.
So, since Si and C are found in the same column, they can substitute each other.
1. Si = C
2. K = Na
3. Nb = V
4. Cu = Ag
5. P = As
6. Mg = Ca
The correct answer are
identify the positive ion and charge
balance the charges
identify the negative ion and charge
