`1` Curie is equal to.

A

`3 xx 10^10` disintegrations/sec

B

`3.7 xx 10^7` disintegrations/sec

C

`5 xx 10^7` disintegrations/sec

D

`3.7 xx 10^10`disintegrations/sec

Text Solution

Verified by Experts

The correct Answer is:
D
(d) Complete reaction will be as follows
`._92X^235 rarr ._82Y^207 + 7._2He^4 + 4 ._-1e^0`
i.e., seven `alpha-`particles and four `beta-`particles will be emitted.
