A sample contains 16. 75 g of the radioisotope U-236 and 50. 25 g of its daughter isotope, Th-232. How long did it take for deca
garri49 [273]

The time taken for the isotope to decay is 46 million years.

We'll begin by calculating the number of half-lives that has elapsed. This can be obtained as follow:

  • Original amount (N₀) = 50.25 g
  • Amount remaining (N) = 16.75
  • Number of half-lives (n) =?

2ⁿ = N₀ / N

2ⁿ = N₀ / N

2ⁿ = 50.25 / 16.75

2ⁿ = 3

Take the log of both side

Log 2ⁿ = 3

nLog 2 = Log 3

Divide both side by log 2

n = Log 3 / Log 2

n = 2

Finally, we shall determine the time.

  • Half-life (t½) = 23 million years
  • Number of half-lives (n) = 2
  • Time (t) =?

t = n × t½

t = 2  × 23

t = 46 million years

Which of these substances most likely dissolve in water? check all that apply.
vlada-n [284]

The answer is:

glucose, a polar organic compound

silver nitrate, an ionic compound

<span>The two have net charges that enable them to attract with water molecules. Water molecules are partly charged because of the arrangement of electron clouds around the molecule. The oxygen atom in the molecule is more electronegative than the two hydrogens. Therefore water is able to form electrostatic attraction forces with the charged molecules</span>
