Chemistry
1 answer:
Alina [70]3 years ago
4 0
Initiation <span>occurs when mRNA, tRNA, and an amino acid meet up inside the ribosome. </span>Elongation occurs when amino acids are continually added to the line, forming a long chain bound together by peptide bonds.

Answer:

The energy decreases as you move from the bottom to the top of the energy pyramid. 90% of the energy entering each step of the pyramid is used up by the consumers, only 10% of the energy get stored. So, when the next level on the pyramid eats them, that 10% gets passed down to them Use the diagram below to answer the question.

Cyclohexane, a commonly used organic solvent, is 85.6% c and 14.4% h by mass with a molar mass of 84.2 g/mol. what is its molecu
puteri [66]

The molecular  formula of   organic solvent  is    <em>C6H12</em>


<h2>calculation</h2><h3>find the empirical formula first as in step 1 and 2</h3>

Step 1: f<em>ind the moles of C and H</em>

  • moles =  % composition/molar mass
  •       from periodic table molar mass of C= 12 g/mol while that of H= 1 g/mol
  • moles is  C is therefore = 85.6/12=  7. 13 moles
  •  moles of H=  14.4/1 - 14.4 moles

  Step 2:  <em>calculate the mole  fraction  by dividing each mole by smallest number of mole(7.13)</em>

  • that is C= 7.13/7.13 = 1

         H=  14.4/7.13 =2

the empirical formula is therefore = CH2

<h2>Then calculate the molecular formula from empirical formula</h2>

step 3: divide the  grams molar mass  by empirical formula mass

               empirical formula mass =  12+(1 x2) = 14 g/mol

    = 84.2/ 14 = 6

step 4: multiply  each of the subscript  within the empirical  formula with the value gotten in step 3

  • that is  [CH2]6 = C6H12  therefore the molecular formula = <u>C6H12</u>

What is the percent composition of nitrogen in sodium nitride
Neporo4naja [7]

Answer:

16.86%

Explanation:

Na3N is sodium nitride.

% of N = mass of N/ molar mass of Na3N *100

% of N = 14/83*100= 16.86%

Calculate the standard entropy of vaporization of ethanol at its boiling point 285 K. The standard molar enthalpy of vaporizatio
Ivanshal [37]

Answer:

standard entropy of vaporization of ethanol = 142.105 J/K-mol

Explanation:

given data

enthalpy of vaporization of ethanol = 40.5 kJ/mol = 40.5 × 10^{3} J/mol

entropy of vaporization of ethanol boiling point = 285 K

to find out

standard entropy of vaporization of ethanol

solution

we get here standard entropy of vaporization of ethanol that is expess as

standard entropy of vaporization of ethanol ΔS = \frac{\Delta H}{T} .............1

here ΔH is enthalpy of vaporization of ethanol and  T is temperature

put value in equation 1

standard entropy of vaporization of ethanol ΔS =  \frac{40.5*10^3}{285}

standard entropy of vaporization of ethanol = 142.105 J/K-mol
