<u>Advantages of Nuclear Fission</u>
-
Nuclear fission provides cheapest energy . Almost 10% of electricity used in the world is obtained from the fission reaction
- It offers a low-emission energy solution since there is no carbon dioxide gas emitted during the nuclear fission reaction
- A well controlled and maintained nuclear reactor can produce energy for 36 to 40 months so works for .
- It is a reliable source of energy as energy is obtained from uranium which is available is plenty.
- It provides very concentrations of energy as it can provide large amount of energy from small amount of fuel.
- The reaction gives less annual mortality rate of any energy resource with 90 deaths per trillion kilowatt hours
<u>Disadvantages of Nuclear Fission
</u>
- It is dangerous and also explosive.
- It creates harmful and radioactive waste products.
- It is not a renewable energy resource like solar and wind energy
- It can develop long-term health issues for people exposed to then radioactive waves.
- It involves high cost in installation of the reactors.
Answer: I think the answer is A
Explanation:
I’m sorry if I’m wrong.
Answer: The volume of the balloon when it is fully cooled by my refrigerator is 0.3 L
Explanation:
To calculate the final volume of the system, we use the equation given by Charles' Law. This law states that volume of the gas is directly proportional to the temperature of the gas at constant pressure.
Mathematically,
where,
are the initial volume and temperature of the gas.
are the final volume and temperature of the gas.
We are given:
Putting values in above equation, we get:
Thus the volume of the balloon when it is fully cooled by my refrigerator is 0.3 L
Complete Question:
Suppose a cobalt atom in the +3 oxidation state formed a complex with two bromide (Br-) anions and four ammonia (NH3) molecules. write the chemical formula of this complex.
Answer:
[Co(NH₃)₄]⁺Br₂
Explanation:
The cobalt atom with +3 oxidation is represented as Co⁺³, and if it's bonded to two bromide ions, and four ammonia molecules. The molecules that are bonded to the metal atom (Co) are called complexing agents.
In the representation, we first put the molecules that surround the metal atom, forming an anion with the oxidation of the metal:
[Co(NH₃)₄]⁺³
Then, the ions are put in the formula. Because there are two bromides ion, each one with 1 minus charge, only 2 plus charged will be neutralized, and the complex will be:
[Co(NH₃)₄]⁺Br₂
Answer: 0.25M
Explanation: Because of the highest concentration of water and, if they are all the same volume, the greatest amount of water assuming it is a solid solute in a water solution.
