Which of the following changes would decrease the rate at which a solid solute dissolves in a liquid solvent? A. Decreasing pressure
B. Decreasing surface area
C. Increasing rate of stirring
D. Increasing temperature

Decreasing surface area of the solid in the liquid.

Explanation:

I don't know how to explain this without using. an example. So, here it is: If you were dipping bread in water, the bread would be completely soaked if you dipped the whole thing, but if you only allowed one part of the bread to be in the water, it would take longer for the water to soak all the way into it. The amount of surface area that is allowed to touch what is making the solid dissolve determines how quickly the whole thing will be dissolved.

The correct answer would be B. Decreasing surface area.

Explanation:

It would be decreasing because the surface area is dissolving, so the surface area is decreasing.

i think   the answer is c hope i'm right

so here we go

atomic mass

239 + 1 = y + 134 + 3 combine like terms

240 = y + 137             subtract 137 from both terms

240 - 137 = y

103 = y

atomic number

94 = z +54 + 0

94 = z + 54               subtract 54 from both sides.

40 = z
