What percent of iodine has decayed if 5 half lives have passed?
goldfiish [28.3K]

Hello!

A half-life is the amount of time it takes half of an element to decay. For example, after one of carbon's half-life, half of carbon would've decayed.

Now, we can calculate how much has decayed if 5 half lives have passed.

1 -> 50% (1) -> 25% (2) -> 12.5% (3) -> 6.25% (4) -> 3.125% (5)

Therefore, there would be 3.125% left of iodine. However, your question is asking what percent has decayed. Therefore, subtract 3.125 from 100% to get your final answer.

100 - 3.125 = 96.875

Therefore, your final answer is 96.875% of iodine has decayed if 5 half lives have passed.

Hope this helps!

A second action potential cannot be generated until ________.
Bingel [31]

Answer:

"Action potential is a rapid rise and subsequent fall in voltage or membrane potential across a cellular membrane with a characteristic pattern."

It is the mode through which a neuron transports electrical signals.

Explanation:

  • Option - (a) is the best choice to choose from,
  • <u>The refractory period :</u>

A second action potential cannot occur until the membrane has recovered or reestablished, this is the refractory period. The absolute refractory period coincides with inactivation of voltage-gated sodium channels which makes it impossible to generate another nerve impulse.
