Calculating the Equilibrium Solubility Constant
A specific metal ion, M²+, forms a relatively insoluble sulfide compound, MS, which dissolves to a very limited extent.
MS(s) = M²+ (aq) + S²-(aq)
The concentration of ions in a saturated solution was found:
[M²+ (aq)] = [S2-(aq)] = 0.000143 mol L-¹.
Calculate Ksp for the compound MS.
Give three significant figures.
Enter your answer in exponential form, for example, enter 0.000000672 as 6.72e-7 with no gaps and the -ve e if power
is -ve.

Calculating The Equilibrium Solubility ConstantA Specific Metal Ion, M+, Forms A Relatively Insoluble

Answers

Answer 1

The solubility product of the substance MS in water is 2.0 * 10^-8.

What is solubility product?

The solubility product is an equilibrium constant that shows the extent to which a solid is dissolved in water.

In this case, the equilibrium is; MS(s) = M²+ (aq) + S²-(aq) but M²+ (aq)] = S^2-(aq)] = 0.000143 mol L-¹.

Thus

Ksp = [0.000143 ]^2 = 2.0 * 10^-8

B. 2-ethyl-1-methylhexanoic acid

Answers

The name of the compound is 2-methyl-3-ethylheptanoic acid.

Naming organic compounds

Looking at the structure, the longest carbon chain is 7. Meaning that the compound is a heptanoic acid.

There are 2 branches. The first one has a single carbon (methyl) while the second one has 2 carbons (ethyl).

The methyl is located on the second carbon (2-methyl) while the ethyl is located on the third carbon (3-ethyl) on the main chain.

Thus, the name of the compound would be 2-methyl-3-ethylheptanoic acid.

C)

Answers

The half-life is the time used by the concentration to get half of its initial value. The cotton cloth is 5097 years old.

What is radioactive decay?

Radioactive decay is the reduction of the initial concentration to the half value. The exponential decay can be given as:

[tex]\rm N(t) = N_{0}e ^{-\lamda t}[/tex]

The decay constant is calculated as:

[tex]\begin{aligned} \lamda &= \rm \dfrac {ln (2)}{t\frac{1}{2}}\\\\&= \dfrac{\rm ln(2)} {5730}\\\\&= 0.0001209\end{aligned}[/tex]

Solving further:

[tex]\begin{aligned}0.22 &= \rm e^{-0.0001209 \times t}\\\\\rm ln 0.22 &= -0.0001209 \times t\\\\\rm t &= \rm \dfrac{log 0.22}{-0.0001209}\\\\&= 5097 \;\rm years\end{aligned}[/tex]

A liquid, solid, or gas's volume is the amount of three-dimensional space it occupies. Although there are many different units that may be used to indicate volume, the most common ones are liters, m³, gallons, milliliters, teaspoons, as well as ounces.

Gases have a volume equal to the internal capacity of the container since they fill their containers to the brim. Containers with a designated volume or one whose interior form is known are frequently used to measure liquids. Measuring cups, graded cylinders, flasks, as well as beakers are a few examples of the tools used to quantify liquid volume.  3.0x10⁻¹²kiloliters represents the greatest volume.

460 grams of Potassium periodate contains 128 grams of Oxygen and 253.9 grams of Iodine.

What is a compound?

A compound is composed of atoms from two or more different elements chemically bonded together in fixed small whole number ratios to each other.

Mass of potassium= 17.0 grams

Mass of Oxygen= 27.8 grams

Mass of Iodine= 55.2 grams.

Mass of Potassium periodate= Mass of Potassium+Mass of Oxygen+Mass of Iodine

Mass of Potassium periodate= 17g+27.8g+55.2g

Mass of Potassium periodate= 100 grams

Therefore, 100 grams of Potassium periodate contains 27.8 grams of Oxygen

1 gram Potassium periodate contains 27.8/100= 0.278 grams of Oxygen

So, 1×460= 460 grams Potassium periodate contains 0.278×460

=128 grams Oxygen

Now,

100 grams of Potassium periodate contains 55.2 grams of Iodine

1 gram of Potassium periodate contains 55.2/100=0.552 grams of Iodine

1×460=460 grams Potassium periodate contains 0.552×460

=253.9 grams of Iodine.

So,  460 grams of Potassium periodate contains 128 grams of Oxygen and 253.9 grams of Iodine.
