If the arrangement of atoms in a substance changes, then the overall chemical properties and reactivities of that particular substance changes as well.
It depends on weather or not the chemicals used can cause problems if not and it's a safe substance than yes they should pour it down the drain
<span>Yes. A mixture in definition is a combination of two or
more elements or compounds. Hence in combining these elements, mixture
is another set of chemical bonding, separately and divergent. Compounds are not
necessary to form mixtures. There is an “or” in the said definition and certain authors to support this claim. These includes examples that can state clearly this
argument, table salt as a mixture of independent elements, Na and Cl. Brass is
composed of zinc and copper. Steel is from carbon and iron. Lastly, you can
have gold, nickel and palladium or platinum to form white gold. </span>
