Answer and explanation;
-Strong acids and bases are defined as compounds that completely ionize in water or aqueous solution. Weak acids and bases only partially dissociate.
A strong acid will fully dissociate in water to form H+ ions.
HCl + H2O---> H3O+ + Cl-
This reaction is non-reversible. After dissolution, only a very very minute concentration of HCl itself remains in the solution, as most of the diluted HCl has dissolved into ions.
Ka = [H+] [Cl-] / [HCl]
The same applied for bases. The only difference is that the base dissociates to form OH- ions instead.
Strong and weak bases will depend likewise on whether the reaction is reversible.
A strong base will completely dissociate to give more OH- ions.
An example of a strong base;
NaOH + H2O ---> Na+ + OH- + H2O
Kb = [Na+] [OH-] / [NaOH]

Answer:
The light reactions, also known as photolysis reactions, convert energy from the sun into chemical energy in the form of NADPH and ATP. These reactions must take place in the light and in chloroplasts of plants.
