A precipitate.
Said insoluble solid would be called a precipitate.
it is ofcourse a solid. diamond and coal are two forms of carbon made compounds.
When sodium carbonate and calcium chloride are combined, a reaction occurs that forms calcium carbonate (a white precipitate), sodium chloride, and water. This reaction is a double displacement reaction where the ions in the two compounds switch partners to form new compounds.
If there are two or more elements or compounds physically combined, then it can no longer be an element.
The mass of the two chemicals are just combined, and are never changed. They may change forms, like from a solid to a gas, but the mass is always the same.
A precipitate is a solid that forms from a solution during a chemical reaction. It is typically formed when two soluble reactants combine to form an insoluble product, which then separates out as a solid. The solid precipitate can be filtered out from the remaining solution.
A chemical reaction that has taken place is likely a precipitation reaction. The formation of a yellow solid suggests the creation of a new compound that is insoluble in the solution and precipitates out.
A molecule.A molecule consists of one or more atoms chemically combined. If the atoms are not the same ie not two oxygen atoms but two oxygen and a hydrogen atom then the a compound is formed.
two or more elements and/or compounds that are physically combined.
alloy if metal?
its,compounds
It is a pure substance composed of two or more elements that are cemically combined.
