Genetic information is encoded in a molecule called DNA?
grandymaker [24]

True

Explanation:

The DNA is the structure in living organisms that encodes genetic information.

DNA = DeoxyriboNucleic Acid.

  • The DNA is made up of a double helix structure of two strands.
  • It is made up of a phosphate group,deoxyribose sugar and four nitrogenous bases.
  • The DNA is contained in the nucleus of every cell.
  • Crick and Watson suggested the molecular structure of the DNA to be a double helix shape.

Keq for the reaction below is 2400. If the initial conditions of the reaction are a 1.0 L flask that contains 0.024 mol NO (g),
podryga [215]

Answer:

The answer to your question is it is not at equilibrium, it will move to the products.

Explanation:

Data

Keq = 2400

Volume = 1 L

moles of NO = 0.024

moles of N₂ = 2

moles of O₂ = 2.6

Process

1.- Determine the concentration of reactants and products

[NO] = 0.024 / 1 = 0.024

[N₂] = 2/1 = 2

[O₂] = 2.6/ 1= 2.6

2.- Balanced chemical reaction

                     N₂ + O₂    ⇒   2NO

3.- Write the equation for the equilibrium of this reaction

                     Keq = [NO]²/[N₂][O₂]

- Substitution

                    Keq = [0.024]² / [2][2.6]

-Simplification

                    Keq = 0.000576 / 5.2

-Result

                    Keq = 1.11 x 10⁻⁴

Conclusion

It is not at equilibrium, it will move to the products because the experimental Keq was lower than the Keq theoretical-

                         1.11 x 10⁻⁴ < 2400
