An aqueous solution of sodium chloride is best classified as \boxed{\left( 2 \right){\text{ homogeneous mixture}}}.

Further Explanation:

Element

A substance that cannot be broken down chemically is known as an element. It contains only one kind of atoms in it. Examples of elements are hydrogen, carbon, and oxygen.

Compound

The substance formed by the chemical combination of two or more atoms is called a compound. Since these are composed of different elements, these can further be broken down into its constituents. The constituent particles lose their properties after the formation of compounds. Examples of compounds are NaCl, \text{NH}_3 and \text{H}_2\text{O}.

Mixture

It is the combination of two or more substances together, but not by chemical means. The constituent particles retain their properties even after the formation of the mixture. Mixtures do not have a fixed formula and these have variable composition. Examples of mixtures are saline solution, concrete, and sand.

Classification of mixture:

1. Homogeneous mixtures

“Homo” means “same”. The mixtures that have the same or uniform composition throughout are termed as homogeneous mixtures. Such mixtures exist in a single phase. Examples of homogeneous mixtures are air, orange juice, and blood.

2. Heterogeneous mixtures

“Hetero” means “different”. The mixtures that have different or non-uniform composition throughout are termed as heterogeneous mixtures. Such mixtures have two or more phases. Examples of heterogeneous mixtures are ice cubes in cola, sand and sugar, and soda.

Sodium chloride is an ionic compound that consists of \text{Na}^+ and \text{Cl}^+ ions. Water is a polar molecule as it contains \text{H}^+ and \text{OH}^- ions in it. So NaCl dissolves in water completely and its aqueous solution exists in a single phase. Therefore, an aqueous solution of NaCl is a homogeneous mixture and option (2) is the correct answer.

What are three units you can measure moler mass in
liraira [26]

By looking at a periodic table, we can conclude that the molar mass of lithium is 6.94g, the molar mass of zinc is 65.38g, and the molar mass of gold is 196.97g. Each of these quantities contains 6.02×1023 atoms of that particular element. The units for molar mass are grams per mole, or g/mol.

So The answers are Lithium, Gold, Zinc

just olya [345]

Answer:

magnesium= +2

aluminum= +3

phosphorous= -3

lithium= +1

fluorine= -1

Explanation:

As fluorine having seven valance electrons in its outer most shell with atomic number nine. And for completing its outer most shell it needs one more electron that is why it form ion of -1 value.

Now  Aluminum has three electrons in its outer most shell with atomic number 13. So it need to lose these three electrons in order to be in stable state that is why it have ion in +3 state.

Same rule apply for other elements too.
