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.

Air has a mass of 1.2g and a volume of 4,555ml. What is the density
coldgirl [10]

Answer:

<h2>Density = 0.00026 g/mL</h2>

Explanation:

The density of a substance can be found by using the formula

<h3>Density(\rho) =  \frac{mass}{volume}</h3>

From the question

mass of air = 1.2 g

volume = 4,555 mL

Substitute the values into the above formula and solve for the density

That's

<h3>Density =  \frac{1.2}{4555}</h3>

= 0.0002634

We have the final answer as

<h3>Density = 0.00026 g/mL</h3>

Hope this helps you

What is the mass in grams of 0.280 mole sample of sodium hydroxide NaOH​
vivado [14]

Answer:

The mass of 0.280 mole sample of sodium hydroxide NaOH​ is 11.2 grams.

Explanation:

To know the mass in grams of 0.280 moles of sample of sodium hydroxide NaOH, you must know the molar mass of the compound, that is, the mass of one mole of a substance, which can be an element or a compound.

So you know:

  • Na: 23 g/mole
  • O: 16 g/mole
  • H: 1 g/mole

So, the molar mass of NaOH is:

NaOH= 23 g/mole + 16 g/mole+ 1 g/mole= 40 g/mole

Then the following rule of three can be applied: if in 1 mole of sodium hydroxide there are 40 grams, in 0.280 moles how much mass is there?

mass=\frac{0.28 moles*40 grams}{1 mole}

mass= 11.2 grams

<u><em>The mass of 0.280 mole sample of sodium hydroxide NaOH​ is 11.2 grams.</em></u>
