Answer:
Explanation:
The formula of density is:
If the formula is rearranged for volume, it becomes:
The mass of the platinum is 38.5 grams.
The density is 21.5 grams per cubic centimeter.
Substitute the values into the formula.
Divide. Note that the grams (g) will cancel each other out.
Round to 2 decimal places (hundredth place). The 0 in the thousandth place tells us to leave the 9 in the hundredth place.
The volume is about <u>1.79 cubic centimeters.</u>
Missing question:
1) the rate of dissolving reaches zero
<span>2) the rate of crystallization reaches zero </span>
3) the rate of dissolving is zero and the rate of crystallization is greater than zero.
<span>4) both the rate of dissolving and the rate of crystallization are equal and greater than zero.

Answer is: 4) both the rate of dissolving and the rate of crystallization are equal and greater than zero.
Silver chloride (AgCl) dissolves and form silver and chlorine ions, in the same time silver and chlorine ions crystallizate and form solid salt silver chloride.
In equilibrium rates of dissolvinf and crysallization and concentration of ions do not change.
It’s 8 electrons. “octa” means 8
% yield = actual yield divided by theoretical x 100
24.6 divided by 55.9 is 0.44
.44 x 100 =44%
