Which is the first step in the dissolving process? a: the solute becomes like the solvent. b: the solute molecules are carried into the solution. c: the solvent molecules surround the solute particles. d: the solvent molecules are attracted to particles at the surface of the solute.

D. The solvent molecules are attracted to particles at the surface of the solute.

For a solute to dissolve, the molecules or atoms that make up the solute particles must separate from each other. This happens when attractions between the solute molecules or atoms and solvent molecules are strong enough to pull the solute particles into solution. Solvent molecules are attracted to the surface of the solute first because the particles in the middle of the solute are too far from the solvent particles to be attracted to.

Correct on the Edge exam.

a: 45.9 meters

b: 4.29 seconds

step-by-step explanation:

a: h(t)=1/2(-9.8)(3)^2+0(3)+90

h(t)=-4.9(3)^2+90

h(t)=-44.1+90

h(t)=45.9 meters

b: 0=1/2(-9.8)(t^2)+0t+90

0=-4.9t^2+90

-90=-4.9t^2

18.37=t^2

t=4.29 seconds

in the second question, the numbers aren't exact, but they're a close approximation.
