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 true since you can test the answer and can use observations to complete it.

when the volume of gas is   changed from   717.73 ml   to 852 ml   the temperature will   change   from 315   c to 452   c

    calculation

this is calculated using the charles law formula

that is,   v1/t1 = v2/t2

          v1=?

        t1 = 315 c   into   kelvin = 315 +273 = 588 k

        v2 = 852   ml

        t2 = 425c + 273 =698 k

make v1   the subject of the formula ( by   multiplying both side by t1)

  v1=( v2 xt1) / t2

v1= (852 ml   x 588 k)/ 698 k= 717.73 ml
