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.

Explanation:
The two isotopes of lithium given are similar in the sense that they have the same atomic number which is 3.
Every kind of an atom of an element have the same atomic number. Atomic number is the number of protons in an atom.
The atoms are different in that they have different mass number because the number of protons they contain are different.
So for isotopes;
- They have the same electronic configuration
- They have similar chemical properties
- But their masses differs
- Their abundance in nature also differs.
Answer :
(a) The speed in Km/hr is,
(b) The speed in mi/min is,
Solution :
The speed of light =
(a) Convert speed of light from m/s to Km/hr
conversions used :
(1 Km = 1000 m)
(1 hr = 3600 sec)
(b) Convert speed of light from m/s to mi/min
conversions used :
Answer:
The concentration of SO₂ will decreases
Explanation:
As you can see in the reaction
2 moles of gas ⇆ 3 moles of gas
Based on Le Châtelier's principle, a change doing in a system will produce that the system reacts in order to counteract the change made.
If the pressure is increased, the system will shift to the left in order to produce less moles of gas and decrease, thus, the pressure.
As the system shift to the left, the concentration of SO₂ will decreases
Answer:
- <em>The mole ratio of C₄H₁₀ and CO₂ is</em><u> 2 : 8, which simplifies to 1 : 4</u>.
Explanation:
The<em> mole ratio</em> is the relative proportion of the moles of products or reactants that participate in the reaction according to the chemical equation.
The chemical equation given is:
- 2C₄H₁₀ + 13O₂ → 8CO₂ + 10H₂O
Once you check that the equation is balanced, you can set the <em>mole ratios</em> for all the reactants and products. The coefficients used in front of each reactant and product, in the balanced chemical equation, tells the mole ratios.
In this case, they are: 2 mol C₄H₁₀ : 13 mol O₂ : 8 mol CO₂ : 10 mol H₂O
Since you are asked about the mole ratio of C₄H₁₀ and CO₂ it is:
- 2 mol C₄H₁₀ : 8 mol CO₂ , which dividing by 2, simplifies to
- 1 mol C₄H₁₀ : 4 mol CO₂, or
