When a solid compound is formed from chemicals which are in solution, it is called a?

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 correct option is c.

isotopes refers to different forms of the same element with the same atomic number but different mass number as a result of difference in their neutron numbers. isotopes have different relative atomic mass but share the same chemical properties.

lol idk man i guess u gotta ask bill nye the science guy
