Answer:
Three half lives corresponds to (12)3 . So a 18 quantity of the original isotope is retained. And the percentage of quantity of a radioactive material that remains after 5 half-lives will be . ∴NN0×100=10032=3.125.
A salt can either be a basic salt or acidic salt. An acidic salt contains a weak base and a strong acid. The acid and base undergoes a neutralization reaction to produce an acidic salt and water. A basic salt contains a weak acid and a strong base. The acid and base undergoes a neutralization reaction to produce a basic salt and water.
