Answer: They retain their chemical properties

Explanation:

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.

For example: Air is a mixture which consists of various gases, water vapors and various particles in solid form which are not present in any fixed ratio, do not combine chemically and thus retain their chemical properties.

Thus the only true statement about substances in a mixture is that they retain their chemical properties

A formula unit is defined as the lowest whole number ratio of

mixer [17]

Answer: $BaF_{2}$

Explanation: Because barium is in Group 2, it forms ions with a charge of +2. Fluorine, in Group 17, form ions with a charge of -1. Cross the charges to get the subscripts (Since Ba has a charge of +2, F has a subscript of 2. Because F has a charge of -1, Ba needs a subscript of 1). Therefore, a formula unit of the compound is $BaF_{2}$ .

Hydrogen bonds between water molecules are responsible for the unique chemical and physical properties of water. True False

N76 [4]

Answer:

True

Explanation:

The physical and chemical properties of a substance depend on the nature of intermolecular forces between its molecules. For instance, water has a high boiling point because of hydrogen bonding between water molecules. Liquid water is denser than ice because of the difference in the nature of hydrogen bonding in liquid water and ice.
