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.

If you are given 720.00 Grams of Oxygen how many moles of Oxygen will you have?
Answer:
720 divided by 2 answer is 556 so answer per is 3.32.3
Explanation:
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.

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%

Q: How does the starting
position affect the speed of a
ball rolling down a ramp?
I NEED HELPP PLSSS ASAP!!!
The force of gravity points straight down, but a ball rolling down a ramp doesn't go straight down, it follows the ramp. Therefore, only the component of the gravitational force which points along the direction of the ball's motion can accelerate the ball. The other component pushes the ball into the ramp, and the ramp pushes back, so there is no acceleration of the ball into the ramp. If the ramp is horizontal, then the ball does not accelerate, as gravity pushes the ball into the ramp and not along the surface of the ramp. If the ramp is vertical, the ball just drops with acceleration due to gravity. These arguments are changed a bit by the fact that the ball is rolling and not sliding, but that only affects the magnitude of the acceleration but not the fact that it increases with ramp steepness.

Calculate the molarity of a solution of monoprotic KHP prepared by mixing a 0.5237 g KHP in 50.0 mL of water .
Answer:
[tex]M=0.0513M[/tex]
Explanation:
Hello!
In this case, since the molarity of a solution is computed by dividing the moles of solute by the volume of solution, we notice we first need the moles of KHP as shown below:
[tex]n=0.5237g*\frac{1mol}{204.22 g} =0.00256mol[/tex]
Next, the volume in liters:
[tex]V=50.0mL*\frac{1L}{1000mL}\\\\V=0.0500L[/tex]
Thus, the molarity turns out to be:
[tex]M=\frac{n}{V}\\\\M=\frac{0.00256mol}{0.05000L} \\\\M=0.0513M[/tex]

"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.
Which change to this process would shift the equilibrium to produce the
maximum possible amount of S03?
2502 +02 2503 + energy
A. Increasing the temperature
B. Decreasing the pressure
C. Removing the O2 as it forms
D. Removing the SO3 as it forms
The change which shift the equilibrium to produce the maximum possible amount of SO₃ is decreasing the temperature.
What is equilibrium principle?According to this principle if any external stress is applied in the equilibrium state then equilibrium will shift towards that side where the external stress will decreases.
In the given chemical equation energy is releases in the form of heat, then in this condition:
Increase in temp will shift the reaction towards the reactant side.Decreasing the pressure will also lead to the decrease in the temperature and in this condition reaction will shift towards product side and will increases the amount of SO₃.Removing the oxygen and SO₃ will not help in increasing the amount of SO₃.Hence decreasing the temperature will produce maximum SO₃.

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.
