What is the mass of sodium nitrate (NaNO3) that will dissolve in 120 g of water at 12°C? O a. 55g
O b. 80g
O a. 969
O d. 439​

they are both synthetic elements

explanation:

d

the best answer is d because the strong cohesion is caused by the ability of water molecules to undergo hydrogen bonding.

a is incorrect because when water solidifies, it becomes   ice, which expands and occupies a bigger volume for the same mass of water in its liquid state.

b is incorrect because water has high surface tension. besides bonding to itself it hydrogen bonds to other molecules at the top decreasing possibility for breaking of attractive forces.

c is incorrect because the water molecule has oxygen which is highly electronegative and so pulls the electron pair towards itself creating a dipole moment, making the molecule polar.

e is incorrect because water has strong adhesion, ability to stick to other molecules such as glass because of this molecules having stronger hydrogen bonding than water.

colorless gas, exhibiting a blue glow when placed in an electric field

b) solid
