If the half-life of iodine-131 is 8. 10 days, how long will it take a 50. 00 g sample to decay to 6. 25 g?

Answers

Answer:

24.4684 days

Explanation:

According to the question the given values are :

T(1/2) for iodine-131 is 5.10 days,

[A]₀ for iodine-131 is 50 grams and,

[A] for iodine-131 is 6.25 grams.

T(1/2)=0.693/k

⇒8.10=0.693/k

⇒k=0.865 .

2.303 log [A]₀/[A]= kt

2.303 log(50.00/6.25)= 0.085×t

⇒t=1/0.085×2.303×log8

t=24.4684 days

Hence, the time it will take to decay is 24.4684 days.

10. Deposition

Weathering is the breaking down or dissolving of rocks and minerals on Earths surface. Once a rock has been broken down, a process called erosion transports the bits of rock and minerals away. Water, acids, salt, plants, animals, and changes in temperature are all agents of weathering and erosion

Erosion is the geological process in which earthen materials are worn away and transported by natural forces such as wind or water. A similar process, weathering, breaks down or dissolves rock, but does not involve movement.

Deposition is the laying down of sediment carried by wind, flowing water, the sea or ice. Sediment can be transported as pebbles, sand and mud, or as salts dissolved in water. Salts may later be deposited by organic activity (e.g. as sea shells) or by evaporation
