Answer: mixture
Explanation:
Compound is a pure substance which is made from atoms of different elements combined together in a fixed ratio by mass.It can be decomposed into simpler constituents using chemical reactions. Example: water
Element is a pure substance which is composed of atoms of similar elements. It can not be decomposed into simpler constituents using chemical reactions.Example: Copper
Mixture is a substance which has two or more components which do not combine chemically and do not have any fixed ratio in which they are present.Example: Alloys
As steel is made up of combination of carbon and chromium and are not present in any fixed ratio , steel is classified as a mixture.
b. Saturated and dilute
c. Saturated and unsaturated
d. Supersaturated and saturated
e. None of these
NaCl(aq)
NaCl(l)
NaCl(g)
Chemists have identified 118 elements. These elements have been organized by their size and property into a chart called the periodic table. All matter is created from these elements which include solid, liquid, and gas. Some elements naturally combine into compounds.
