<u>Answer:</u> The value of 
is 324
<u>Explanation:</u>
We are given:
Initial pressure of 
= 1.00 atm
The chemical equation for the conversion of to 
follows:
<u>Initial:</u> 1
<u>At eqllm:</u> 1-x 4x
We are given:
Equilibrium partial pressure of 
Evaluating the value of 'x', we get:
The expression of for the above reaction follows:
Putting values in above expression, we get:
Hence, the value of is 324

Answer:
19.9 mol
Explanation:
Use <em>Avogadro’s number</em> to convert formula units of CaI₂ to moles of CaI₂.
1 mol CaI₂ ≡ 6.022 × 10²³ formula units CaI₂
Moles of CaI₂ = 1.20 × 10²⁵ × (1 /6.022 × 10²³)
Moles of CaI₂ = 19.9 mol
Answer:
7.5 gm left
Explanation:
Bismuth-210 has a half life of 5 days
15 days is 15/5 = 3 half lives
since half the amount is left in 5 days or 1 half life
(1/2) x (1/2) x (1/2) the staring amount would be left in
3 half lives. so 1/8 is left
(1/8) x 60.0 = 7.5 gm left
