How many kilograms of nitrogen are present in a 3.50 L sample of N2O
Answers
There are 2.72 kilograms of nitrogen present in a 3.50 L sample of N₂O.
To find the mass of nitrogen in N₂O, we must calculate the number of moles of N₂O.
[tex] n_{N_{2}O} = \frac{m_{N_{2}O}}{M{N_{2}O}} [/tex] (1)
Where:
[tex] m_{N_{2}O}[/tex]: is the mass of N₂O
[tex]M_{N_{2}O}[/tex]: is the molar mass of N₂O = 44.013 g/mol
The mass of N₂O can be founded from the density:
[tex] d = \frac{m}{V} [/tex] (2)
Where:
d: is the density of N₂O = 1.22 g/mL
V: is the volume = 3.50 L = 3500 mL
Then, the mass of N₂O is (eq 2):
[tex] m = d*V = 1.22 g/mL*3500 mL = 4270 g [/tex]
Now, the number of moles of N₂O is (eq 1):
[tex] n_{N_{2}O} = \frac{4270 g}{44.013 g/mol} = 97.02 \:moles [/tex]
Knowing that in 1 mol of N₂O we have 2 moles of N, the number of moles of nitrogen is:
[tex] n_{N} = \frac{2\: moles \: N}{1 \:mol \: N_{2}O}*n_{N_{2}O} = \frac{2\: moles \: N}{1 \:mol \: N_{2}O}*97.02 \:moles \:N_{2}O = 194.04 \: moles [/tex]
Finally, with the number of moles of N we can find its mass:
[tex] m = n_{N}*M_{N} = 194.04 \:moles*14.007 g/mol = 2717.9 g = 2.72 kg [/tex]
Therefore, there are 2.72 kilograms of nitrogen.

Formic acid, from the Latin formica, is the acid present in ants sting. What is the
concentration of HCOO" at equilibrium if the initial concentration of formic acid,
HCOOH, is 1.35 M (Kg = 1.7 x 10-4).
Answers
For the reaction of deprotonation of formic acid, the concentration of HCOO⁻ at equilibrium is 0.0151 M if the initial concentration of formic acid is 1.35 M.
The reaction of deprotonation of formic acid is the following:
CHOOH + H₂O ⇄ HCOO⁻ + H₃O⁺
At the equilibrium we have:
CHOOH + H₂O ⇄ HCOO⁻ + H₃O⁺ (1)
1.35 - x x x
The acid equilibrium constant for this reaction is:
[tex] K_{a} = \frac{[HCOO^{-}][H_{3}O^{+}]}{[CHOOH]} = 1.7 \cdot 10^{-4} [/tex] (2)
Entering the values of [CHOOH] = 1.35-x, [HCOO⁻] = [H₃O⁺] = x, into equation (2) we have:
[tex] 1.7 \cdot 10^{-4} = \frac{[HCOO^{-}][H_{3}O^{+}]}{[CHOOH]} = \frac{x^{2}}{(1.35 - x)} [/tex]
[tex]1.7 \cdot 10^{-4}(1.35 - x) - x^{2} = 0[/tex]
After solving the above quadratic equation and taking the positive value for x (concentrations cannot be negative), we have:
[tex] x = [HCOO^{-}] = [H_{3}O^{+}] = 0.0151 M [/tex]
Therefore, the concentration of HCOO⁻ at equilibrium is 0.0151 M.

Answers
Explanation:
The added greenhouse gases absorb the heat. They then radiate this heat. Some of the heat will head away from the Earth, some of it will be absorbed by another greenhouse gas molecule, and some of it will wind up back at the planet's surface again. With more greenhouse gases, heat will stick around, warming the planet.

What is the process whereby stars create elements heavier than hydrogen?
atomic growing
atom splitting
nucleosynthesis
hydrogenation
Answers
Answer:
nucleosynthesis
Explanation:
The correct answer is nucleosynthesis.
How do stars create heavier elements?After the hydrogen in the star's core is exhausted, the star can fuse helium to form progressively heavier elements, carbon and oxygen, and so on, until iron and nickel are formed. Up to this point, the fusion process releases energy. The formation of elements heavier than iron and nickel requires an input of energy.
What was the process of the formation of heavy elements?In a supernova explosion, neutron capture reactions take place (this is not fusion), leading to the formation of heavy elements. This is the reason why it is said that most of the stuff that we see around us comes from stars and supernovae (the heavy elements part).

Under conditions of very high pressures, what would you predict about the experimental volume of the gas?
The volume would be lower than predicted by the Ideal Gas Law
The volume would be higher than predicted by the Ideal Gas Law
The volume would be exactly the same as predicted by the Ideal Gas Law
Answers
Under conditions of very high pressures, the volume would be lower than predicted by the Ideal Gas Law.
According to the kinetic theory of gases, a gas spreads out to fill the volume of the container holding it. Hence a gas does not have a definite volume due to the fact that there is no inter-molecular interaction between gas molecules.
When the gas is subjected to very high pressure, inter-molecular interactions become significant leading to a decrease in the volume of the gas.
Therefore, when subjected to high pressure, the experimental volume would be lower than predicted by the Ideal Gas Law.
