Chemical reactions are characterized by the formation of new products, and the making and breaking of strong chemical bonds.
The percentage composition of CF4 is %C = 13.64% and %F = 86.36%
The solution are as follows:
Molar mass of CF4 = 88
<span>molar mass of C = 12 </span>
<span>molar mass of F = 4x19 = 76 </span>
<span>% C = 12/88 x 100 = 13.64% </span>
<span>% F = 76/88 x 100 = 86.36%</span>
The frequency of a photon of red light with wavelength 4.50 x 10−7m is 6.67 x 1014Hz
It is fresher because of new transportation techniques and refrigerated trailers.
