The molar solubility of zns is 1.6 Ã 10-12 m in pure water. Calculate the ksp for zns.
Oksi-84 [34.3K]

Answer:

The solubility product of zinc sulfide is 2.56\times 10^{-24}.

Explanation:

Solubility of the zinc sulfide = S=1.6\times 10^{-12}

ZnS\rightleftharpoons Zn^{2+}+S^{2-}

                S        S

The expression of solubility product is given by :

K_{sp}=[Zn^{2+}]\times [S^{2-}]

K_{sp}=S\times S=S^2

=1.6\times 10^{-12}\times 1.6\times 10^{-12}=2.56\times 10^{-24}

The solubility product of zinc sulfide is 2.56\times 10^{-24}.

Which state of matter (solid, liquid, or gas) has molecules that move the fastest?
Margaret [11]
Gas.

Solid is the slowest; it stays together, so the molecules don't move much.
Liquid is the middle; it stays together for the most part, but it can move.
Gas is the fastest; they can move all over the place!

As the solar oven operate, what happens to the kinetic energy of the particles of matter in the air and the food inside
umka2103 [35]

Answer:

The average kinetic energy of the particles of matter in the air and the food inside increases

Explanation:

The relationship between the average Kinetic energy and temperature is given by the following formula

K = 3×R×T/(2×N_A)

Where;

R = The universal gas constant = 8.314 J/(mol·K)

N_A = Avogadro's number = 6.02 × 10²³ atoms/mol

T = The temperature of the gases in Kelvin

Given that a solar oven is able to raise the temperature to about 200°F, food cooks slower than in a conventional oven

However, given that the temperature and the average kinetic energy are directly related, the average kinetic energy rises.
