Answer:
26.2ml
Explanation:
This is a delusion calculation. But before performing the delusion we need to know the concentration the polarity of the original solution. The original solution was prepared by taking .021 mg of ibuprofen and dissolving it in one mil leader. So to calculate the concentration, we need to take the moles of ibuprofen, which can be calculated by taking the milligrams divided by 1000 to get grams and then divided by the molar mass to get moles and dividing the moles of ibuprofen by the leaders of the solution. One mil leader can be calculated, Can be converted into a leader by dividing by 1000. We then get a polarity of 1.018 times 10 to the negative for Mueller Than to carry out the dilution. We have a 1.018 times 10 to the negative for Mueller solution and one mil leader of it. We want to prepare 375 times 10 to the negative six molar solution. And so we need to figure out what the new total volume will be Rearranging. This equation gives us a total volume of 27.15 million l but we already have one mil leader of solution. So we need to add to that The 27.15 -1 or the 26.15 ml. The answer then of the choices available would be 26.2 ml
In the solution, 26.2 ml of water should add to achieve a 3.75 μm solution of ibuprofen.
How to make a solution to ibuprofen?Ibuprofen 0.02 mg was dissolved in 1 mil of lead to create the original solution. In order to compute the concentration, we must first determine the moles of ibuprofen.
This may be done by dividing the milligrams by 1000 to obtain grams, then dividing those grams by the molar mass to obtain moles, and finally dividing the moles of ibuprofen by the solution's leaders.
By dividing by 1000, r may be determined and converted to a leader. Then, for Mueller to operate, we have a polarity of 1.018 times 10 to the negative.
Therefore it needs 26.2 ml of water need to make the solution of 3.75 μm of ibuprofen.

which of the following molecules can cross the lipid bilayer of a membrane directly, without a transport protein or other mechanism? select all that apply.
Answer:
Explanation:
Molecules can cross the lipid bilayer of a membrane directly, without a transport protein or other mechanism - water, oxygen, carbon dioxide, and lipids.
Osmosis is transport in which the movement of a solvent occurs through a semipermeable membrane from a less concentrated solution into a more concentrated one without any protein.
Diffusion is a process where the molecule moves from one part to another part through the membrane.
Diffusion and osmosis are types of passive transport that do not require energy
This kind of movement does not involve transport proteins or other complex mechanisms.
Large polar molecules like glucose, amino acids, ions move through a membrane with the help of proteins
small non-polar molecules such as oxygen, carbon dioxide by diffusion and small polar molecules like water
large non-polar molecules like lipids can cross the membrane without the help of proteins by osmosis.
Thus, Molecules can cross the lipid bilayer of a membrane directly, without a transport protein or other mechanism - water, oxygen, carbon dioxide, and lipids.

why do scientists observe blueshift in certain stars?
The Doppler effect allows finding the answer for the blue shift of some stars is:
The star closing in on us
The Doppler effect is the change in the frequency perceived by the relative movement of the emission and the receiver, in the case of light we must use relativistic relations and the expression is
[tex]f = f_o \sqrt{\frac{1- \frac{v}{c} }{1+ \frac{v}{c} } }[/tex]
Where f and fo are the observed and emitted frequencies, respectively, c the speed of light and v the relative speed between the source and the observer, this speed is positive if they move away and negative if they approach.
The speed light is related to frequency and wavelength
c = λ f
[tex]f = \frac{c}{ \lambda}[/tex]
we substitute
[tex]\frac{1}{\lambda } = \frac{1}{lam_o } \ \sqrt{\frac{1- \frac{v}{c} }{1+ \frac{v}{c} } }[/tex]
[tex]\lambda = \lambda_o \ \sqrt{ \frac{1+ \beta }{1- \beta } }[/tex]
with [tex]\beta = \frac{v}{c}[/tex]
The magnitude of β is always less than 1
Let's analyze the effect of the speed between the observer and the emitter on the perceived wavelength, we have two:
The two bodies are moving away, in this case the velocity is positive, let's substitute[tex]\lambda_1 = \lambda_0 \ \sqrt{\frac{1+| \beta|}{1- |\beta|} }[/tex]
We can see that the numbering of the root increases and the dominated decreases, so the root increases its value, consequently
[tex]\lambda_1 > \lambda_o[/tex]
This process is called redshift.
The two bodies are approaching, in this case the velocity is negative, we substitute
[tex]\lambda_2 = \lambda_o \ \sqrt{\frac{1- |\beta| }{1+ |\beta| } }[/tex]
We see that the root decreases its value, consequently
[tex]\lambda_2 < \lambda_o[/tex]
This is called the blueshift.
In this exercise, indicate that we have a blueshift, which is why the star is approaching us.
In conclusion, using the Doppler effect we can find the answer for the blue shift of some stars is:

In thunder as in sunshine, I stand at ease. False negotiator, away! See, the scroll of the storm is rolled back; the house is unharmed; and in the blue heavens I read in the rainbow, and will not make war on man's earth."

Consider the chemical equation. CuCl2 2NaNO3 Right arrow. Cu(NO3)2 2NaCl What is the percent yield of NaCl if 31.0 g of CuCl2 reacts with excess NaNO3 to produce 21.2 g of NaCl? Use Percent yield equals StartFraction actual yield over theoretical yield EndFraction times 100.. 49.7% 58.4% 63.6% 78.7%
Answer:
D. 78.7% on edge 2020
Explanation:
i got 100
The percent yield of NaCl is 78.7 %
CuCl₂ + 2NaNO₃ → Cu(NO₃)₂ + 2NaCl
How NaNO₃ is determined to be in excess?If the NaNO₃ is determined to be in excess, the limiting reagent is the chloride. We convert the mass to moles:
31 g . 1mol / 134.45g = 0.230 moles
Ratio is 1:2, so we can make a rule of three to determine the theoretical yield
1 mol of copper (II) chloride reacts to produce 2 moles of sodium chloride.
Then you can find out how much NaCl 31.0g of CuCl₂ should produce using stoichiometry. Divide 31.0g by the molar mass of CuCl₂ (134.446g/mol) to get 0.2306mol CuCl₂. Than multiply 0.2306mol CuCl₂ by 2 to get 0.4612mol NaCl.
Than multiply 0.4612mol by the molar mass of NaCl (58.45g/mol) to get 26.95g of NaCl.
that means that 100% yield would give you 26.95g of NaCl so to find percent yield divide 21.2 by 26.95 to get 0.7867 which is 78.7% yield
Then, 0.230 moles of CuCl₂ will react to produce (0.230 .2) /1 ) = 0.461 moles of NaCl → we convert the moles to mass → 0.461 mol . 58.45 g / 1mol = 26.9 g
To find percent yield we do → (Yield produced / Theoretical yield) . 100
(21.2 g / 26.9 g) . 100 = 78.7 %
