Answer:
The partial pressure of nitrogen is 0.402 atm.
Explanation:
Given data:
Number of moles of helium = 1 mol
Number of moles of nitrogen = 2 mol
Total pressure of mixture = 0.60 atm
Partial pressure of nitrogen = ?
Solution:
First of all we will calculate the mole fraction of nitrogen.
mole fraction of nitrogen = moles of nitrogen / total number of moles
mole fraction of nitrogen = 2 mol / 3 mol = 0.67
Partial pressure of nitrogen:
P₁ = [ n₁ /n(t)] × Pt
P₁ = 0.67 × 0.60 atm
P₁ = 0.402 atm
To find the partial pressure of nitrogen in a mixture, calculate the mole fraction of nitrogen and multiply it by the total pressure of the mixture. In this case, the partial pressure of nitrogen is 0.40 atm.
The question is about determining the partial pressure of nitrogen in a mixture of helium and nitrogen based on Dalton's Law of Partial Pressures. First, we find the mole fraction of nitrogen, which is the ratio of moles of nitrogen to the total moles in the mixture. In this scenario, the mole fraction (XN2) is 2 moles of nitrogen divided by the total moles (1 mole of helium + 2 moles of nitrogen), which equals 2/3.
Then we use Dalton's Law, which states that the partial pressure of nitrogen (PN2) can be found by multiplying the mole fraction by the total pressure of the mixture. Therefore, the partial pressure of nitrogen is 0.60 atm (total pressure) multiplied by 2/3 (mole fraction of nitrogen), yielding a partial pressure for nitrogen of 0.40 atm.

Under which color of light will plants be least likely to make food?
red
blue
orange
green
Answer:
The color of light in which plants are less likely to produce food is green.
Explanation:
Photosynthesis is the process by which plants take advantage of sunlight to convert it into chemical energy, necessary to manufacture their nutrients, their growth and development.
Plants do not absorb all the colors of the light spectrum, since due to their pigments they absorb colors with specific wavelengths. Green plants do not absorb the color green, but reflect it —due to the chlorophyll pigment— which gives the green color to those leaves.
For this reason, the light that plants take least advantage of to produce food is green light.
Other options:
The colors blue, orange and red can be absorbed by the plant, to a lesser or greater degree.
Answer:
it would be green
