a 50g sample of radioactive iodine-131 has a half-life of 8.0 days. After 32 days, how much is left?

Answers

Answer 1

Answer:

The correct answer is = 3.125 gram.

Explanation:

The half-life of iodine-131 is 8 days as given. The half life of is the required time to which a radioactive comond or element left half of its initial life quantity which means that after 8 days, half of the sample (50 gm of iodine 131) would have decayed and half would be left undecayed.

now it is ask that how much amount of iodine 131 left after 32 days, so

32 days = 4 half lives of iodine 131 (8 days * 4 = 32 days)

Thus, after 1st half life = 50/2 = 25gm

2nd half life = 25/2 = 12.5

3rd half life = 12.5/2 = 6.25

and at last fourth half live = 6.25/2 = 3.125

Thus, the correct answer is = 3.125 gram.

O True

Answers

Hi! I’m pretty sure it’s false because I’m not sure what level of education has to do with health conditions but it could be true. I’m sorry I couldn’t give a direct answer.
It is true to some extent. Because level of education would to some extent determine the type of occupation one will be in. And some occupation involves hazardous working environment that long time exposure causes harsh consequences to one l’s health through the development of different chronic health conditions.
Take for an example, a migrant worker with low socio-economic status, since he is doing such type of job meant he has low educational level. working in a mine meant inhalation to the dust and smoke Frequently. And for prolonged period of time it leads to various respiratory infections, from bronchitis to asthma. You can search for research articles on this area for a more detailed explanation.
