Answer:
Pb(CH3COO)2(s) -------> Pb^2+(aq) + 2CH3COO^- (aq)
Explanation:
Recall that a strong electrolyte is an electrolyte that dissociates completely in solution. Hence, if we say that lead(II) acetate is a strong electrolyte we are actually saying that lead(II) acetate ,dissociates completely in solution to yield lead II ions and acetate ions.
This implies that the reaction equation shown in the answer section tends to go to completion since lead(II) acetate is a strong electrolyte.
Answer:
₉₂U²³⁸ → ₉₀Th²³⁴ + ₂He⁴ + energy
Explanation:
Alpha decay:
Alpha radiations are emitted as a result of radioactive decay. The atom emit the alpha particles consist of two proton and two neutrons. Which is also called helium nuclei. When atom undergoes the alpha emission the original atom convert into the atom having mass number less than 4 and atomic number less than 2 as compared to parent atom the starting atom.
Properties of alpha radiation:
Alpha radiations can travel in a short distance.
These radiations can not penetrate into the skin or clothes.
These radiations can be harmful for the human if these are inhaled.
These radiations can be stopped by a piece of paper.
₉₂U²³⁸ → ₉₀Th²³⁴ + ₂He⁴ + energy
