1. Chlorofluorocarbons (CFCs) are of interest because of their ability to destroy ozone molecules. A carbon-chlorine bon din the CFC molecule can be broken by sunlight, leaving a highly reactive free radical which then goes on to destroy the surrounding ozone molecules. The energy of a C-Cl bond is 328 kJ/mole. Calculate the wavelength of light needed to break a bond in a single molecule. In which region of the spectrum (infrared, visible, UV) does this wavelength fall

See explanation

Explanation:

Energy of the photon (E) = 328 * 10^3/6.02 * 10^23 = 5.45 * 10^-19 J

Recall that E = hc/λ

h = Plank's constant = 6.36 * 10^-34 Js

c = speed of light = 3 * 10^8 m/s

λ = ??

λ = hc/E

λ = 6.36 * 10^-34 * 3 * 10^8/5.45 * 10^-19

λ = 3.5 * 10^-7 m

This falls into the UV region of the spectrum

it is important to conserve water because there is very limited amount of freshwater here on earth and if we are not smart about how we use it we will only be runnning out of our supply faster than neccessarry.
