Question

Po decays with alpha particle to pb with a half life of 138.4 day. If 1g of po is placed in a sealed tube, how much helium will accumulate in 69.2 day

Answer 1

Answer:

84Po210 decays with α-particle to 82Pb206 with a half life of 138.4 day. If 1.0 g of 84Po210 is placed in a sealed tube, the volume of helium ... day. Therefore, no. of halves, n = t/t1/2 = 69.2/138.4 = 1/ 2.

Answer 2

Explanation:

4Po210 decays with α to 82Pb206 with a half life of 138 4 days If 1 0 gm of Po210 is placed in a closed tube , how much helium accumulate in 69 2 ... ·
