Answer:
1.33 x 10⁻³ mol/L
Explanation:
The solubility of a gas in a liquid is directly proportional to its partial pressure .This is know as Henry´s law and is given by the formula:
S(g) = Kh x P
where S = solubility of the gas
Kh = henry´s constant for the gas
P = partial pressure of the gas above solution
we are told to assume that the composition of the air in the tank is the same as on land, hence its partial pressure and we know nitrogen composition in air is 78 %, so the partial pressure of N₂ is:
P N₂ = 0.78 x 2.73 atm = 2.13 atm
Now we can calcualte the solubility as follows:
S N₂ = 6.26 x 10⁻⁴ mol / L·atm x 2.13 atm = 1.33 x 10⁻³ mol/ L
Answer: What occurs during telophase? A cell has a single line of chromosomes.
Explanation:
In metals, some of the electrons (often one per atom) are not stuck to individual atoms but flow freely among the atoms. Of course, that's why metals are such good conductors of electricity. Now if one end of a bar is hot, and the other is cold, the electrons on the hot end have a little more thermal energy- random jiggling- than the ones on the cold end. So as the electrons wander around, they carry energy from the hot end to the cold end, which is another way of saying they conduct heat.
Here, sodium is a metal which possesses an extra (valence) electron carries the heat around its body as it is a free electron, which enables sodium to conduct thermal energy.
Hope this help :)
The formula of citric acid is:
CO2H

HO - C - CH2CO2H

C - CH2 CO2H
I bolded the 4 hydrogens that can be subsituted by sodium.
Three of those hydrogens belong to carboxyl group (- CO2H) and one to a hydroxyl group (- OH).
You need to take into account that 4 H will form 2 H2 molecules.
So, the answer is that 2 moles of molecules will be formed from 1 mole of citric acid molecules.
