A huge balloon is filled with 1.208 m3
of dinitrogen, more commonly known as nitrogen gas
(N2).
It has a pressure of 1.207 x105
Pa and a temperature of 313.5 K. What is the mass of the
dinitrogen?
Answers
1.208 m3 of nitrogen gas (N₂), also known as dinitrogen, is placed inside a sizable balloon. It has a temperature of 313.5 K and a pressure of 1.207 x 105 Pa. The mass of dinitrogen (N₂) in the balloon is approximately 1715.88 grams.
To calculate the mass of dinitrogen (N₂) in the balloon, we can use the ideal gas law equation:
PV = nRT
Where:
P = pressure of the gas (in Pa)
V = volume of the gas (in m³)
n = number of moles of the gas
R = ideal gas constant (8.314 J/(mol·K))
T = temperature of the gas (in K)
First, we need to rearrange the equation to solve for the number of moles (n):
\(\[n = \frac{PV}{RT}\]\)
Now we can substitute the given values into the equation:
P = 1.207 x 10⁵ Pa
V = 1.208 m³
R = 8.314 J/(mol·K)
T = 313.5 K
\([n = \frac{1.207 \times 10^5 \text{ Pa}}{\cancel{\text{Pa}}} \cdot \frac{1.208 \text{ m}^3}{\cancel{\text{m}^3}} \cdot \frac{\cancel{\text{J}}}{8.314 \text{ J}/\cancel{\text{mol}\cdot\text{K}}} \cdot \frac{\cancel{\text{K}}}{313.5 \cancel{\text{K}}} = 0.500 \text{ mol}]\)
Simplifying the expression:
n ≈ 61.21 mol
Finally, to calculate the mass of dinitrogen, we need to multiply the number of moles by the molar mass of N₂, which is approximately 28 g/mol:
Mass = n * molar mass
Mass ≈ 61.21 mol * 28 g/mol
Mass ≈ 1715.88 g
Therefore, the mass of dinitrogen in the balloon is approximately 1715.88 grams.

What is the molecular formula of a compound with a percent composition of 49.47% C, 5.201% H, 28.84% N, and 16.47% O, and a molar mass of 194.2 g/mol?
Answers
Answer:
Explanation:
The molecular formula is the true chemical formula of a covalent molecular compound, and a multiple of the empirical formula. We can use the molar mass, along with the molar empirical mass, determined from the empirical formula, to determine the molecular formula of the compound.
Using, the percentage composition of each element, we can say: In each 100g of the compound, there is 49.47g (C), 5.201g (H), 28.84g (N), and 16.47g (O).
Therefore, we can now find the number of moles of each element, in 100g of compound. number of moles (n) = mass present (m) ÷ molar mass (M). Molar mass can be found using a standard IUPAC Periodic Table.
n(C) = m/M = 49.47/12.01 = 4.1191 mol
n(H) = m/M = 5.201/1.008 = 5.1597 mol
n(N) = m/M = 28.84/14.01 = 2.0585 mol
n(O) = m/M = 16.47/16.00 = 1.0293 mol
Since the empirical formula is one in which the proportions of each element are expressed in the simplest mole ratio, therefore:
C : H : N : O = 4.1191 : 5.1597 : 2.0585 : 1.0293
Divide each ratio by 4.1191 =
1 : 1.00985 : 0.4997 : 0.249, which is approximately equal to:
1 : 1 : 0.5 : 0.25 = 2 : 2 : 1 : 0.5 = 4 : 4 : 2 : 1
Therefore, empirical formula = C₄H₄N₂O.
Using empirical formula, we can calculate molar empirical mass, which is found by summing the molar atomic weights.
molar empirical mass = 4(12.01)+4(1.008) + 2(14.01) + 16.00 = 96.092.
The molar empirical mass is double the molar mass, and therefore, molecular formula must be half the empirical formula.
Therefore, molecular formula = C₂H₂NO

Answers
The tapetum lucidum, a reflective substance found in the choroid coat of cows, is responsible for a cow's ability to see at night by reflecting light that is absorbed by the retina back into the retina.
Many vertebrates and certain other creatures have a tissue layer in their eyes called the tapetum lucidum. There is a retroreflector directly behind the retina. It increases the amount of visible light that is available to the photoreceptors by reflecting it back through the retina (although slightly blurring the image). Some animals have excellent night vision thanks to the tapetum lucidum. The majority of these creatures are nocturnal, particularly the carnivores, while others are deep-sea creatures.
Some spider species have comparable adaptations. Humans are haplorhine primates, which do not have a tapetum lucidum and are nocturnal. Animals can see in lower light than they otherwise could thank to the presence of a tapetum lucidum. Iridescent tapetum lucidum reflects light roughly in accordance with thin-film optics' interference principles.

g the free energy associated with the proton gradient that develops across the inner mitochondrial membrane as a result of the electron transport chain is 23.3 kj per mole of protons. if fadh2 is the only electron donor to the electron transport chain, how many moles of fadh2 would be required to produce a proton gradient in which exactly one mole of protons have been pumped across the membrane, assuming we start with no gradient? the standard reduction potential of fadh2 is 0.10 v, and that of o2 is 0.81 v. select the closest value from the options below. a) 3 mol fadh2 d) 0.17 mol fadh2 b) 1 mol fadh2 e) 5.8 mol fadh2 c) 0.5 mol fadh2
Answers
The number of moles of FADH₂ required to produce a proton gradient is 0.17 mol. This can be calculated through the free energy and potential difference. Thus, the correct option is D.
What is the required number of moles of FADH₂?
There are 6.022 × 10²³ protons per mole of H⁺. Therefore, one mole of H⁺ contains 1 mole of protons.
The change in potential between FADH₂ and O₂ is: ΔE°' = E°'(O₂) - E°'(FADH₂)
ΔE°' = 0.81 - 0.10
ΔE°' = 0.71 V
ΔG for electron transfer from FADH₂ to O₂ is: ΔG°' = -nFΔE°'
where, n = number of electrons, F = Faraday's constant (96,500 J/V), and ΔE°' is the change in potential between the two half-cells.
We know that n = 2 (since FADH₂ transfers two electrons to O₂).
ΔG°' = -2 × (96,500) × (0.71)
ΔG°' = -137,860 J/mol
ΔG° = -nFΔΨ
where, n = number of protons, F = Faraday's constant (96,500 J/V), and ΔΨ is the change in potential across the membrane. We know that n = 1 (since we want to pump one mole of H⁺ across the membrane).
ΔΨ = ΔG°/(nF)
ΔΨ = (-137,860)/(1 × 96,500)
ΔΨ = -1.43 V
ΔG = ΔG° + RTlnQ
where, R = gas constant (8.31 J/molK), T = temperature in Kelvin (298 K), and Q = reaction quotient.
Since the reaction is at standard conditions, Q = 1 (since all the reactants and products are in their standard states).
ΔG = ΔG°
ΔG = -137,860 J/mol
ΔG = -137.86 kJ/mol
23.3 kJ/mol = n × (1.43 V)
n = 0.17
Therefore, 0.17 mol of FADH₂ is required.
Therefore, the correct option is D.

to produce a .458 M solution after
dilution with 50.0 mL of water. What
is the molarity of the stock solution?
Answers
Answer:
0.202M
Explanation:
you will want to use C₁V₁=C₂V₂ to solve for this.
C₁ is the initial concentration, in this problem it is .458 mol/L or M
V₁ is the initial volume, so it will be the 22.0 mL or 0.0220L
C₂ is the new concentration but here it is unknown.
V₂ is the new volume which is 50.0 mL or 0.0500L.
1. So now we plug this information in to the equation:
\((.458 mol/l)(0.0220L)=(C_{2} )(0.0500L)\)
2. We then do algebra to get C₂ alone:
\(C_{2} =\frac{(.458 mol/L)(0.0220L)}{(0.0500L)} =0.20152 mol/L or M\)
The liters cancel out and take note of the significant figures, there are 3 digits in all numbers in the question, so that means your answer must contain 3 sig figs. The answer 0.0202 rounded.
** instead of converting the mL to L you can also just keep them mL since they will be crossed out anyway. You will still get the correct answer.

why is water an excellent solvent for most ionic compounds and polar covalent molecules but not for non-polar compounds?
Answers
Water is an excellent solvent for most ionic compounds and polar covalent molecules but not for non-polar compounds because of its content loaded with certain chemical properties that make it a highly effective solvent. Water molecules are polar, and due to their dipolar nature, the oxygen atom carries a negative charge while the hydrogen atoms carry a positive charge.
The polarity of the water molecule allows it to interact with and dissolve other polar and ionic substances.When an ionic compound is dissolved in water, the ions of the compound dissociate into individual charged species (cations and anions), and these charged species are solvated by water molecules. The polarity of the water molecule allows it to interact with the ions by attracting the positively charged ions to the negative end of the water molecule and vice versa.
The same is true for polar covalent molecules, which have a net dipole moment. Water molecules can interact with these molecules, forming a solvation layer around them. On the other hand, non-polar compounds lack a net dipole moment, so they don't interact with the water molecules. Instead, non-polar compounds interact with each other via van der Waals forces, making it more challenging for them to dissolve in water.

Answers
To find the difference in pH, we can subtract pH1 from pH2:pH2 - pH1 = -log(3)Using a calculator, we can evaluate the right side of the equation:-log(3) ≈ 0.477Therefore, the pH increases by about 0.477 units when the concentration of positive hydrogen ions is decreased by two thirds.
When the concentration of positive hydrogen ions is decreased by two thirds, the pH increases by about 0.477 units. This can be calculated using the formula:
pH
= -log[H+],
where [H+] represents the concentration of positive hydrogen ions.Using this formula, we can find the initial pH:
pH1
= -log[H+1]
where [H+1] is the initial concentration of positive hydrogen ions. Let's say the initial concentration is x. Then:
pH1
= -log[x]
Now, if the concentration is decreased by two thirds, the new concentration is (1/3)x. Using this value, we can find the new pH:
pH2
= -log[(1/3)x]
= -log(x) - log(3)
Using the formula for pH1, we can substitute -log(x) for pH1:
pH2
= pH1 - log(3).
To find the difference in pH, we can subtract pH1 from pH2:
pH2 - pH1
= -log(3)
Using a calculator, we can evaluate the right side of the equation:
-log(3) ≈ 0.477

D) ZnBr2
Answers
Answer:
ZnBr2
Explanation:
KNO3 + LiOH -------> no reaction
This is because KNO3 and LiOH completely ionize.in water and form neutral solutions.Since both are neutral no reaction occurs
NH4Cl + LiOH -----> NH3 (aq) + H2O (l) + LiCl(aq)
None of the above products are precipitates
Ca(C2H3O2)2 + 2LiOH -----> Ca(OH)2 (aq) + 2LiC2H3O2 (aq)
ZnBr2 + 2LiOH -----> Zn(OH)2 (s) + LiBr2 ( aq)
Zn(OH)2 thus formed is a white precipitate
However when excess LiOH is added Zn(OH)2 precipitate will dissolve to give a clear solution of Li2ZnO2 .
You can remember this by the fact that Na,K,Rb,Cs,Ca,Sr,Ba hydroxides are soluble in water and all other hydroxide are precipitated in water
Zn(OH)2 (s) + 2 LiOH ------> Li2ZnO2(aq) + 2 H2O ( l)
The only compound that will form a precipitate with LiOH would be ZnBr2
Precipitation reactionsThese are double displacement reactions in which precipitates are produced. Precipitates are insoluble solids formed from the combination of ions in aqueous solutions.
In this case, a reaction between LiOH and ZnBr2 would be as follows;
2LiOH + ZnBr2 ----------> 2LiBr + Zn(OH)2 (s)
Zn(OH)2 is an insoluble salt and will precipitate out in the solution.
