At equilibrium the concentrations of:
[HSO₄⁻] = 0.10 M;
[SO₄²⁻] = 0.037 M;
[H⁺] = 0.037 M;
There is initially very little H+ and no SO₄²⁻ in the solution. A salt is KHSO₄⁻. All KHSO₄⁻ will split apart into K⁺ and HSO₄⁻ ions. [HSO₄⁻] will initially be present at a concentration of 0.14 M.
HSO₄⁻ will not gain H⁺ to produce H₂SO₄ since H₂SO₄ is a strong acid. HSO₄⁻ may act as an acid and lose H⁺ to form SO₄²⁻. Let the final H⁺ concentration be x M. Construct a RICE table for the dissociation of HSO₄²⁻.

Explanation:
<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.
