Answer:
Chlorine exists as gaseous state while potassium chloride as a solid
0.25 g of U-235 isotope will be left.
<h3><u>
Formula used :</u></h3>
N = N₀/2
where,
N = amount of U-235 left after n-half lives = ?
N₀ = Initial amount of the U-235 = 1.00 g
n = number of half lives passed = 2ⁿ
Using the formula, we can conclude:
N = 1/2² = 0.25
Thus, 0.25 g of U-235 isotope will left .
<h3><u>The concept of half lives</u></h3>
A half-life is the amount of time it takes for something to go from 100% to 50%. The phrase is most frequently used in reference to radioactive decay, which happens when energetic atomic particles that are unstable lose momentum. There are 29 elements that have been shown to be capable of going through this process.
Like pharmaceuticals, advertising campaigns, and a variety of other things, information likewise has a half-life.
