Morgan has an equal amount of Sand and Salt. They take the two piles of material and combine them together. Morgan says that this combination of Sand and Salt is a Compound. Do you agree with Morgan?

I DISAGREE with Morgan

Explanation:

A compound is made up of two or more elements which are usually chemically bonded together. Such elements can only be separated by a chemical process and not by physical processes like filtration and decantation.

Examples of compounds includes:

--> Table salt(NaCl) this is a chemical compound which contains elements such as sodium and chlorine which are chemically bonded together.

--> water(H2O): this contains elements such as hydrogen and oxygen chemically bonded together

But substances such as sand is not a compound but a mixture which contains natural deposits of silicon dioxide, small rocks and other organic substances which are not chemically bond together.

Therefore, the combination of equal parts of salt and sand will lead to the formation of a HETEROGENEOUS MIXTURE not a compound.

This is a type of mixture in that made up of different compositions.
