Health hazards that are associated with uranium mining

Uranium is a radioactive substance that is used for generation of the thermal energy in the nuclear power plant. But uranium mining and processing is associated with numerous health effects related with the exposure to the radioactive decay products. The person may either inhale, ingest or the toxins can also seep inside the tissues through cut. The radioactive waste are responsible for causing drastic mutations and cancer.

<h3>What is Uranium mining ?</h3>

The process of removing uranium ore from the earth is known as uranium mining. In 2019, 53,656 tonnes of uranium were produced globally. The top three uranium producers are Kazakhstan, Canada, and Australia, who together produce 68% of the world's uranium.

  • The impacts of uranium mining are extensive, causing radioactive dust, radon gas, water-borne poisons, and higher background radiation levels in the environment. In order to produce nuclear energy and nuclear weapons, uranium must first be mined.

Natalka [10]

The maximum amount of XeF4 that could be produced is 0.5 moles.

XeF4 = Xe (g) 2 F2 (g) (g)

Xe and F2 have a mole ratio of 1:2. Because of this, the reaction would be limited by F2 when there is 1 mole of Xe and 1 mole of F2.

<h3>What is mole ratio?</h3>

The mole ratio is the ratio of any two compounds' mole amounts that are present in a balanced chemical reaction.

A comparison of the ratios of the molecules required to accomplish the reaction is given by the balancing chemical equation.

A mole ratio is a conversion factor used in chemical reactions to link the mole quantities of any two compounds. A conversion factor's numbers are derived from the balanced chemical equation's coefficients.

How is percent by mass and concentration related?
Julli [10]
You can have a solution of hydrogen peroxide that might say 10% that means that 10% per mass of the hydrogen peroxide solution is the hydrogen peroxide the rest is water.

concentration is the amount of mass in the solution eg 5gdm-3

Answer:

See answer below

Explanation:

To do this, you need to write down the chemical reaction giving place here.

As this is to explain the thermodynamics of the borax-borate reaction, the general reaction is as follow:

Na₂B₄O₅(OH)₄.8H₂O(s) <---------> 2Na⁺(aq) + B₄O₅(OH)₄²⁻(aq) + 8H₂O(l)

Where:

Na₂B₄O₅(OH)₄.8H₂O(s) = Borax

B₄O₅(OH)₄²⁻(aq) = Borate ion

Now, in order to calculate the concentration of borate, this compound undergoes a titration with HCl. The reaction that takes place here is:

B₄O₅(OH)₄²⁻(aq) + 2HCl + 3H₂O <---------> 4H₃BO₃(aq) + 2Cl⁻(aq)

According to this reaction, it takes 2 moles of HCl to completely react with the borate ion, therefore, the expression to calculate the concentration will be:

2 nHCl = nB₄O₅(OH)₄²⁻

2M₁V₁ = M₂V₂

Replacing the data of concentration and volume of both compounds we have:

2 * 0.1006 * 23.33 = 10M₂

M₂ = 2 * 0.1006 * 23.33 / 10

M₂ = 0.4693 M

This is the concentration of the borate. Now, to calculate the Ksp we need to write the equilibrium reaction taking place with the borax:

Na₂B₄O₅(OH)₄.8H₂O(s) <---------> 2Na⁺(aq) + B₄O₅(OH)₄²⁻(aq) + 8H₂O(l)

Ksp = [B₄O₅(OH)₄²⁻] [Na⁺]²

As we already have the concentration of borax, we can also know the concentration of sodium. If we call concentration as "s" (Stands for solubility), and rewrite the expression of Ksp:

Ksp = s * (2s)²

Finally, replacing the value of the concentration we have:

Ksp = (0.4693) (2*0.4693)²

Ksp = 0.4693 * 0.881

Ksp = 0.4134

Hope this helps
