Which of the following is a physical property of the salt crystals shown here? A. they are gas
B. they cannot burn
c. they are a liquid
D. they are clear white

As the explanation i think the answer is D

Explanation:

Transparent and colourless in crystalline form – rather like ice. Crystallises in the isometric system, usually in the form of cubes. Soluble in water (35.6g/100g at 0°C and 39.2g/100g at 100°). Slightly soluble in alcohol, but insoluble in concentrated hydrochloric acid.Physical properties: Sodium chloride is a white crystalline solid with a density of 2.16 g/mL, and a melting point of 801 °C. It is also available as aqueous solutions of different concentrations, called saline solutions. Chemical properties: Sodium chloride is readily soluble in water and other polar solvents.

explanation:

venn diagram is pictorial representation with of circles showing the relation between two finite sets or things. the intersection part of two circles conveys the relation present in between those sets or things.

here in the venn diagram of sand and salt two circles represent sand and salt. but the area falling under the intersection of these circle represents the mixture of sand and salt.

so, in a venn diagram the mixture will be placed in a middle that is in between the intersection of two circles.
