Answer:
Xe will have the highest partial pressure
Explanation:
Using Dalton's law of partial pressures for ideal gases
p=P*x
where
p= partial pressure , P= total pressure and x = mole fraction = n / ∑n
since the number of moles is related with mass through
n= m/M
where
m= mass and M= molecular weight
then if m is the same for all the gases
x = m*M/ ∑ (m*M) = m*M/ m∑ M = M/∑ M
thus
p=P*x = P*M/ ∑ M
for the 3 gases
p₁=P*x₁ = P*M₁/ (M₁+M₂+M₃)
p₂=P*x₃ = P*M₂/ (M₁+M₂+M₃)
p₂=P*x₃ = P*M₃/ (M₁+M₂+M₃)
then for gasses under the same pressure (P=constant) and same mass (m=constant) , p is higher when the molecular weight is higher . Therefore Xe will have the highest partial pressure
The major group of organic chemicals that has double the number of hydrogen atoms as carbon or oxygen atoms [chemical formula (ch2o)n] is carbohydrates.
<h3>What are carbohydrates?</h3>
Carbohydrates are biological macromolecules that function as macronutrients by providing energy, which are composed of simple carbon-based molecules linked by glycosidic bonds.
In conclusion, the major group of organic chemicals that has double the number of hydrogen atoms as carbon or oxygen atoms [chemical formula (ch2o)n] is carbohydrates.

3600 years.
Since 65% of the carbon-14 is remaining, we need to get the logarithm to base 2 of 0.65 to determine how many half lives have expired. So: log(0.65)/log(2) = -0.187086643/0.301029996 = -0.621488377
So we know that 0.621488377 half-lives has gone by to the bone sample. Now we just need to multiply by the half-life of carbon-14 which is 5730 years. So: 0.621488377 * 5730 = 3561.128399 years. Rounding to the nearest 100 years gives us 3600 years.
