The reasons for sleep are poorly understood. The statement is true.
What is sleep?Sleep is a regular, repeatable state of lowered sensitivity to external energy followed by detailed and consistent physiologic changes which help the brain to function effectively by coordinating with other parts.
Sleep plays important role in one's life . A regular and proper sleeping pattern helps an individual to perform routine tasks with better productivity.
Sleep allows your body to get recharged to perform the routine work with full energy and helps in maintaining the mental and physical well-being of an individual by eliminating the risk of health diseses.
Lack of sleep and changes in the sleeping pattern causes fatigue and laziness due to insufficient sleep and the body does not relax people as sleep helps an individual to feel fresh and relaxed from all the hustle.
The reasons why an individual gets sleep can be due to recharging or to be relaxed or function properly. Therefore the statement is true.

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 %

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.

The chemical formula for Nickel (III) oxide is [tex]Ni_{2}O_{3}[/tex].
Given data:
The chemical formula for nickel (III) oxide is [tex]Ni_{2}O_{3}[/tex]. This formula indicates that each molecule of nickel (III) oxide consists of two nickel (Ni) atoms and three oxygen (O) atoms.
Nickel is in its +3 oxidation state. The oxidation state represents the charge of the element in the compound, and in nickel (III) oxide, each nickel atom carries a +3 charge.
The presence of three oxygen atoms in the compound is indicated by the subscript 3 after the O in the formula. This means that there are three oxygen atoms for every two nickel atoms in the compound.
Hence, the chemical formula [tex]Ni_{2}O_{3}[/tex] represents nickel (III) oxide.

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:
The star closing in on us

CPR is an acronym for cardiopulmonary resuscitation and it can be defined as an act performed by professionals or experts, in order to revive a patient whose respiratory system is failing.
Basically, cardiopulmonary resuscitation (CPR) should typically be performed for patients who are still consciousness and breathing because they still have life in them.
The cardiopulmonary resuscitation (CPR) performed on infants is quite different from that being performed an adults because infants are fragile and have less developed organs.
During CPR, an infant's chest should be compressed lightly and a shallow rescue breathing given to him or her.
In conclusion, the first step of performing CPR on infants after checking that he or she is consciousness and breathing is to deliver gentle (shallow) rescue breaths to protect the baby’s lungs.

when attempting to control someone or something, do people compromise their own freedom in the process?
Perception differs for a lot of people. I believe that attempting to control someone or something, will not make one compromise their own freedom in the process.
Why attempt to control someone if you are going to loose your right to do whatever you want or be free. One's aim to control is to be able to do what you want.Freedom is the right of an individual to be free and even though it can be compromised by the evil intensions of other people, it is not right to so it to yourself. Lossing your freedom over something is not worth it. Though some people do compromise their freedom for anything but not in all situations.So therefore, I believe that people do not compromise their freedom at all and Lost of freedom is not what a person desires.
