g It takes to break a carbon-carbon single bond. Calculate the maximum wavelength of light for which a carbon-carbon single bond could be broken by absorbing a single photon. Round your answer to significant digits.

The maximum wavelength of light for which a carbon-carbon single bond could be broken by absorbing a single photon is 349 nm.

Note: The question is incomplete. The complete question is given below:

It takes 348./kJmol to break a carbon-carbon single bond. Calculate the maximum wavelength of light for which a carbon-carbon single bond could be broken by absorbing a single photon.

Round your answer to 3 significant digits.

Explanation:

From the question, it takes 348 kJ/mol to break a carbon-carbon triple bond.

Thus, the energy required to break 1 mole of carbon-carbon triple bond = 348 kJ = 348,000 J/mol.

For a single carbon-carbon single bond, energy required is given as E.

E = Energy required per mol/number of atoms per mole, NA

NA = 6.02 × 10²³

E = 348000 J / 6.02 × 10²³ = 5.7 × 10-¹⁹ J

This energy will be equivalent to the wavelength of the photon of light absorbed by the atom.

From Planck's equation, E = hc/λ

Where c = velocity of light = 3.0 × 10⁸ m/s

h is Planck's constant = 6.63 × 10-³⁴ Js

λ is wavelength of photon

Making λ subject of the formula:

λ = hc/E

λ = (6.63 × 10-³⁴ Js × 3.0 × 10⁸ m/s)/5.7 × 10-¹⁹ J

λ = 3.49 × 10-⁷m = 349 nm

The maximum wavelength of light for which a carbon-carbon single bond could be broken by absorbing a single photon is 349 nm.

answer; i do believe the correct answer is (river); /// good luck

assuming that your periodic table has eighteen columns, you should highlight   the four elements in the third column from the left of the table.

neutral atoms of elements after calcium contain d electrons. the energy of d orbitals of a particular main shell lies between the energy of the s and p orbitals of the next main shell. for example, electrons in the have energy higher than those in the orbital while lower than those of the orbital.

by the aufbau principle, electrons fill orbitals one at a time, starting from those of the lowest energy. the orbital is therefore filled right after orbitals and before orbitals.  

potassium has electron configuration and calcium . the s orbital of a main shell holds a maximum of two electrons. the next element would thus have the electron configuration and satisfy the requirements.

a neutral atom of the element contains three electrons on top of the most recent noble gas element. it should thus be placed in the third column of the periodic table. both scandium and yttrium would satisfy the conditions. an aufbau diagram indicates that the 4f orbital is filled before the 5d. however, it appears that exceptions exists for both lanthanum and actinium. neutral atoms of the two d-block elements also demonstrate the and should be highlighted as well.
