Which of the below best explains what happens when salt dissolves in water?
A. The polar solvent molecule surrounds the positive sodium ions and the negative chloride ions.
B. The solute and the solvent particles do not interact.
C. The solute and solvent particles form a crystalline structure.
D. The polar solvent molecules surround only the positive sodium ions.

Option A. The polar solvent molecule surrounds the positive sodium ions and the negative chloride ions.

Explanation:

When a salt say NaCl dissolved in water, the solvent molecules surround both the Na+ and Cl-. The Na+ are surrounded by OH- and the Cl- are surrounded by H+.

i think it is d. e because the next one is igneous.

you need to take a look at the periodic system in order to sort these elements into pairs that would most likely exhibit similar chemical properties. first, you need to find elements that are found in the same group (groups are vertical in the periodic system), and then to see whether they have the same valence number. if they meet these criteria, they will have similar properties.

the first pair: ne (neon) and kr (krypton), are noble gases found in group 8

the second pair: li (lithium) and k (potassium), found in group 1

the third pair: s (sulfur) and te (tellurium), found in group 6
