The longest wavelength of radiation used to break carbon-carbon bonds is 344 nm.
<u>Explanation:</u>
The longest wavelength of radiation can also be stated as the minimum radiation frequency required to cut carbon-carbon bond should be equal to the threshold energy of the carbon-carbon bonds.
The threshold energy will be equal to the binding energy of the carbon-carbon bonds. As it is known that carbon-carbon bonds exhibit a binding energy of 348 kJ/mole, the threshold energy to break it, is determined as followed.
First, we have to convert the energy from kJ/mol to J, i.e., energy for the carbon-carbon molecules,

As,

So,

Thus,
is the longest wavelength of radiation used to break carbon-carbon bonds.
D. Budgeting time, avoiding stress, and prioritizing.
A spring that obeys Hooke's law has a spring force constant of 272 N/m. This spring is then stretched by 28.6 cm
If a bus travels 30 km in 1/2 hr, then in one hr, he can travel twice the distance.
30*2=60 km
Final answer: 60 km per hr
