When the procedure calls for making a more dilute solution of an acid, or mixing an acid with other solutions, what is the corre

ct order of steps? Select one: a. Neither of these methods is safe. b. Always Add Acid - Either add all of the water or non-acid component first, or add a significant portion, before adding the acid to the mixture.

a 160 milligram sample of a radioactive isotope decays to 10 kilograms in 12 years. what is the half life of this element
Shkiper50 [21]

Answer:

3 years

Explanation:

Given data:

Initial amount of sample = 160 Kg

Amount left after 12 years = 10 Kg

Half life = ?

Solution:

at time zero = 160 Kg

1st half life = 160/2 = 80 kg

2nd half life = 80/2 = 40 kg

3rd half life = 40 / 2 = 20 kg

4th half life = 20 / 2 = 10 kg

Half life:

HL = elapsed time / half life

12 years / 4 = 3 years
