Translation is the conversion of RNA to protein. The conversion of RNA to DNA is called reverse transcription.
What do you mean by Proteins?Proteins may be defined as natural-appearing, extremely complex substances that consist of amino acid residues joined by peptide bonds.
The process of translation occurs in the cytoplasm of the cells, while the process of transcription occurs in the nucleus itself.
The conversion of DNA to RNA is called transcription. While the proteins are never directly converted from DNA, it involves both processes of transcription followed by the translation.
Therefore, translation is the conversion of RNA to protein.

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%

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.
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.

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.

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.

Answer:
[IBr] = 0.049 M.
Explanation:
Hello there!
In this case, according to the balanced chemical reaction:
[tex]I_2+Br_2\rightarrow 2IBr[/tex]
It is possible to set up the following equilibrium expression:
[tex]K=\frac{[IBr]^2}{[I_2][Br_2]} =0.0110[/tex]
Whereas the the initial concentrations of both iodine and bromine are 0.50 M; and in terms of [tex]x[/tex] (reaction extent) would be:
[tex]0.0110=\frac{(2x)^2}{(0.50-x)^2}[/tex]
Which can be solved for [tex]x[/tex] to obtain two possible results:
[tex]x_1=-0.0277M\\\\x_2=0.0245M[/tex]
Whereas the correct result is 0.0245 M since negative results does not make any sense. Thus, the concentration of the product turns out:
[tex][IBr]=2x=2*0.0249M=0.049M[/tex]

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.
