Answer: The correct answer is methanol.

Explanation:

Molecular compounds are defined as the compounds which are formed by the sharing of electrons between the different atoms that are combining. They do not break easily or the bond between them cannot be broken down easily. Thus, they do not form ions. These molecules are formed when two or more non-metals combine.

Ionic compounds are defined as the compounds which are formed by the donating of electrons from one atom to another. They form ions.

From the given options:

Option 1: Sulfate ion

Chemical formula for this ion is $SO_4^{2-}$ . The given ion is a polyatomic ion and thus is known as ionic compound.

Option 2: Calcium chloride

The chemical formula for this compound is $CaCl_2$ . It is formed by the combination of calcium and chlorine ions. Thus, they will form ionic compound.

Option 3: Methanol

The chemical formula for this compound is $CH_3OH$ . It is formed by the sharing of electrons between carbon, hydrogen and oxygen atoms. Thus, it is considered as a molecular compound.

Option 4: Oxygen

This is formed by the sharing of electrons between two oxygen atoms. Thus, this is considered as a non-polar covalent compound.

Hence, the correct answer is methanol.

Which sample of matter is classified as a solution? 1. H2O(s) 2. H2O(l) 3. CO2(g) 4. CO2(aq)

lys-0071 [83]

Answer : Option 4) $CO_{2}_{(aq)}$

Explanation : $CO_{2}_{(aq)}$ is the only sample of matter which can be classified as a solution. As the solution can be defined as a liquid mixture which contains a minor component (the solute) that is uniformly distributed within the major component (the solvent).

In this case, the solute is $CO_{2}$ which is dissolved in water which acts as an solvent. Also, it has a subscript which is aq. which means aqueous, is often given to the solution in which the solvent is water.
