The diffusion of solutes through transport proteins in the plasma membrane is referred to as facilitated diffusion. Passive transport is a subset of facilitated diffusion. Facilitated diffusion is still passive transport even though it uses transport proteins.
In contrast to passive diffusion, assisted diffusion does not result in the carried molecules dissolving in the phospholipid bilayer. Proteins instead allow the delivered molecules to pass through the membrane without coming into contact with its hydrophobic interior.
Materials move across the plasma membrane with the aid of membrane proteins during facilitated transport, also known as facilitated diffusion.

Consider the following reaction:
Mg(s) + 2 HCl (aq) → H2(g) + MgCl2(aq)
If 3.65 mol of magnesium and 3.65 mol of hydrochloric acid are reacted, how many
moles of hydrogen gas are produced?
Answer: 1.825 moles of hydrogen gas are produced.
Explanation:
The balanced chemical equation is:
[tex]Mg(s)+2HCl(aq)\rightarrow H_2(g)+MgCl_2(aq)[/tex]
According to stoichiometry :
2 moles of [tex]HCl[/tex] require = 1 mole of [tex]Mg[/tex]
Thus 3.65 moles of [tex]HCl[/tex] will require=[tex]\frac{1}{2}\times 3.65=1.825moles[/tex] of [tex]Mg[/tex]
Thus [tex]HCl[/tex] is the limiting reagent as it limits the formation of product and [tex]Mg[/tex] is the excess reagent.
As 2 moles of [tex]HCl[/tex] give = 1 mole of [tex]H_2[/tex]
Thus 3.65 moles of [tex]HCl[/tex] give =[tex]\frac{1}{2}\times 3.65=1.825moles[/tex] of [tex]H_2[/tex]
Thus 1.825 moles of hydrogen gas are produced.

Calculate the molecular weight of guanylate at pH 7. Show your work. Draw the structures of three different tautomers of hypoxanthine. One of the nonstandard nucleotides that appears moderately often in rRNA and tRNA is dihydrouridine. Which carbon atoms within the uracil moiety of this nucleotide have two hydrogens each attached to them
Answer:
Explanation:
The molecular formula for Guanylate is [tex]\mathbf{C_{10} H_{14} N_5O_8 P}[/tex]
This is calculated by the addition of the atomic weight of all the atoms taking part in the molecule.
i.e. (10 × C) + (14 × H) + (5 × N) + ( 8 × O) + (1 × P)
= (10 × 12) + (14 × 1) + (5 × 14) + ( 8 × 16) + (1 × 30)
= 120 + 14 + 70 + 128 + 30
= 362 g/mol
The diagram for the tautomers of hypoxanthine can be seen in the image attached below.
Dihydrouridine is available and can be seen in tRNAs and rRNAs. It is an exceptionally preserved and adjusted base. It is a pyrimidine nucleoside that is shaped by the expansion of two hydrogen atoms to uridine. By the expansion of two hydrogen atoms to uridine makes it completely soaked and no presence of any two-fold or double bond.
Catalytic reduction of carbon-carbon double bonds in Dihydrouridine synthase occurs at positions 5 and 6 on the uridine base.
Hence, 5 and 6 carbon particles inside the uracil moiety of this nucleotide have two hydrogens each connected to them.

Kingsley then adds 44.12 mL of NaOH to 250.00 mL of the HCOOH solution. The neutralization reaction resulted in 0.091 moles of HCOOH and 0.036 moles of HCOO- left in solution. Determine the pH of the resulting solution.
Answer:
pH = 3.34
Explanation:
We can calculate the pH using Henderson-Hasselbach's equation:
pH = pKa + log[tex]\frac{[HCOO^-]}{[HCOOH]}[/tex]for HCOOH, pKa = 3.75.
We can calculate [HCOO⁻] and [HCOOH] using the given number of moles for each one and the final volume:
Final Volume = 44.12 mL + 250 mL = 294 mL294 mL / 1000 = 0.294 L[HCOO⁻] = 0.036 mol / 0.294 L = 0.122 M[HCOOH] = 0.091 mol / 0.294 L = 0.310 MThen we proceed to calculate the pH:
pH = 3.75 + log[tex]\frac{0.122}{0.310}[/tex]pH = 3.34The pH of the resulting solution is 3.34.
Calculation of the pH of the solution:Since
Final Volume = 44.12 mL + 250 mL = 294 mL
Now
= 294 mL / 1000
= 0.294 L
Now
[HCOO⁻] = 0.036 mol / 0.294 L = 0.122 M
[HCOOH] = 0.091 mol / 0.294 L = 0.310 M
So, the pH should be
= 3.75 + log0.122/0.310
= 3.34
hence, The pH of the resulting solution is 3.34.

Answer:
1. Percentage yield is 64.75%
2. Atom economy is 48.39%
Explanation:
1. Determination of the percentage yield
Experimental yield = 24.8 g
Theoretical yield = 38.3 g
Percentage yield =?
Percentage yield = Experimental yield /Theoretical yield × 100
Percentage yield = 24.8 / 38.3 × Percentage yield = 2480 / 38.3
Percentage yield = 64.75%
2. Determination of the atom economy.
The balanced equation for the reaction is given below:
6CO₂ + 6H₂O —> C₆H₁₂O₆ + 6O₂
Next, we shall determine the mass of CO₂, H₂O and C₆H₁₂O₆ from the balanced equation.
Molar mass of CO₂ = 12 + (16×2)
= 12 + 32
= 44 g/mol
Mass of CO₂ from the balanced equation = 6 × 44 = 264 g
Molar mass of H₂O = (2×1) + 16
= 2 + 16
= 18 g/mol
Mass of H₂O from balanced equation = 6 × 18 = 108 g
Molar mass of C₆H₁₂O₆ = (6×12) + (12×1) + (6×16)
= 72 + 12 + 96
= 180 g/mol
Mass of C₆H₁₂O₆ from the balanced equation = 1 × 180 = 180 g
Next, we shall determine the total mass of the reactants. This is illustrated below:
Mass of CO₂ = 264 g
Mass of H₂O = 108 g
Total mass of reactants =?
Total mass of reactant = Mass of CO₂ + Mass of H₂O
Total mass of reactant = 264 + 108
Total mass of reactant = 372 g
Finally, we shall determine the atom economy. This can be obtained as follow:
Mass of desire atom (C₆H₁₂O₆) = 180 g
Total mass of reactants = 372 g
Atom economy =.?
Atom economy = mass of desire atom / total mass of reactant × 100
Atom economy = 180/372 × 100
Atom economy = 48.39%

A sample of hydrogen gas occupies
1.0 L at 760 torr in a balloon. If the
temperature is kept constant, which
expression represents the volume of
hydrogen gas in liters when the
pressure is raised to 860 torr?
A 860 + 760
B 860 – 760
C 860 / 760
D 760 / 860
When the pressure of a sample of hydrogen gas increases from 760 torr to 860 torr, the expression D 760 / 860 represents the volume of hydrogen gas in liters.
What does Boyle's law state?Boyle's law is a law stating that the pressure of a given mass of an ideal gas is inversely proportional to its volume at a constant temperature.
A sample of hydrogen gas occupies 1.0 L at 760 torr in a balloon. We can calculate the volume when the pressure is increased to 860 torr using Boyle's law.
P₁ × V₁ = P₂ × V₂
V₂ = (P₁/P₂) × V₁
V₂ = (760 torr/860 torr) × 1.0 L = 0.88 L
where,
P₁ and V₁ are the initial pressure and volume.P₂ and V₂ are the final pressure and volume.When the pressure of a sample of hydrogen gas increases from 760 torr to 860 torr, the expression D 760 / 860 represents the volume of hydrogen gas in liters.

a. The bubbles will shrink, and some may vanish.
b. The bubbles will grow, and more may appear.
c. The bubbles won't change.
d. I need more information to predict what will happen to the bubbles.
2. A student has two unopened cans containing carbonated water. Can A has been stored in the garage () and can B has been stored in the fridge (). The student opens one can at the time, both cans make a fizz.
a. Can A will make a louder and stronger fizz than can B.
b. Can B will make a louder and stronger fizz than can A.
c. The fizz will be the same for both cans.
d. There is not enough information to predict which can will make the louder fizz.
Answer:
The correct answer is -
1. a) The bubbles will shrink, some may vanish.
2. a) Can A will make a louder and stronger fizz than can B.
Explanation:
In the first question, it is given that the bottle is not opened and therefore, squeezing the bottle filled with a carbonated drink will increase the pressure on the carbonated liquid which forces the bubbles to dissolve or displace or vanish as it moves to empty space.
Thus, the correct answer would be - The bubbles will shrink, some may vanish
In the second question, there are two different conditions for two different unopened cans of carbonated water that are different temperatures one at the garage with higher temperature and one in the fridge at low temperature. As it is known that higher the temperature less will be solubility of gas in liquid so gas in can A will be less soluble which means it has more gas and it will make louder and stronger fizz than B which was stored at low temperature.
thus, the correct answer would be - Can A will make a louder and stronger fizz than can B.

"How many grams of CaCl2 would be dissolved in 1.0 L of a 0.10 M solution of CaCl2? "
Answer:
2365 g
Explanation:
The mass of CaCl₂ will be 110.98 grams, this can be calculated by using the molarity formula.
MolarityIt is defined as the ratio of a number of moles of solute to the volume of solution in liters.
It is given by:
M= n/V
What information do we have?
V= 1.0 L
M= 1.0 M
Molar mass of CaCl₂ = 110.98g/mol
To find:
m=?
M= n/V
n= M/V
n= 1 mole
A Number of moles is the ratio of mass over the molar mass.
n = m/ M
1 mole= m / 110.98 g/mol
m= 110.98 grams
Thus, the mass of calcium chloride is 110.98 grams.

Suppose that you are performing a titration on a monoprotic acid. Titration of this monoprotic acid required a volume of 0.1L of the base being used. If the same volume of a diprotic acid would instead have been used (same volume of a diprotic acid versus the originally used monoprotic acid), and if we assume furthermore that the concentration of the diprotic acid and the monoprotic acids are equal, how does the volume of base required to reach the endpoint for the diprotic acid compare to the volume of base required to reach the endpoint for the monoprotic acid?
A) More base is likely required to reach the endpoint for the diprotic acid than for the monoprotic acid under these conditionsB) Less base is likely required to reach the endpoint for the diprotic acid than for the monoprotic acid. C) Exactly the same amount of base is required for both monoprotic and diprotic acids under the situations described here.D) A completely different indicator will need to be used here.
Answer: A) More base is likely required to reach the endpoint for the diprotic acid than for the monoprotic acid under these conditions
Explanation:
The monoprotic acid (HA) has a valency of 1 and diprotic acid [tex](H_2A)[/tex] has a valency of 2.
As the concentration and volume of the diprotic acid and the monoprotic acids are equal.
The neutralization reaction for monoprotic acid is:
[tex]HA+BOH\rightarrow BA+H_2O[/tex]
The neutralization reaction for diprotic acid is:
[tex]H_2A+2BOH\rightarrow B_2A+2H_2O[/tex]
Thus more number of moles of base are required for neutralization of diprotic acid and thus the volume required will be more as concentration and volume of the diprotic acid and the monoprotic acids are equal.
