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.

Answer:
Explanation:
Mass of uncrystallized product = (Mass of watch glass + filter paper + crystallized product) - (Mass of watch glass + filter paper)
Mass of uncreystaliized product = 109.03 gm - 105.98 gm
Mass of uncrystaliized product = 3.05 gm
For methyl benzoate;
mass = 3.08 g
no of moles = 3.08 g/ 136.15 g/mol = 0.0226 mole
It is possible for the formation of 1 mole of nitro methyl benzoate from a mole of methyl benzoate.
moles of nitro methyl benzoate that can be formed from 0.0226 moles of methyl benzoate = 0.0226 moles
∴
mass of nitro methyl benzoate = 0.0226 mol × 181.15 gm /mol
mass of nitro methyl benzoate = 4.098 gm
For HNO_3 solution:
mass = 1.42 gm/ml × 2.0 ml
mass = 2.84 gm
Mass of HNO3 in 2.84 gm solution
= 1.9596 gm
Moles of HNO3 =
= 0.0311 mole
1 mol of HNO_3 can be formed from 1 mole of nitro methyl benzoate
Thus; moles of nitro methyl benzoate that can be formed from 0.0311 mole of HNO_3 = 0.02256 mole
The mass for nitro methyl benzoate can now be determined as:
= 0.0311 mole × 181.5 gm/mole
= 5.634 gm
Since the mass formed from methyl benzoate is lesser, then methyl benzoate serves as the limiting reagent.
The mass obtainable from the LR = 4.098 gm
Answer: The work done on the gas mixture is
Explanation:
According to first law of thermodynamics:
=Change in internal energy
q = heat absorbed or released
w = work done on or by the system
w = work done on the system = {Work done on the system is positive when the final volume is lesser than initial volume }
w =
w = {1Latm=101.3J}
The work done on the gas mixture is
Answer:
The first one is 102.33 g/ml
Explanation:
307 divided by 3 gets u the answer 102.33(repeated)
