Answer:
c = λ x ν
v =c/λ=(3*10e8)/(5.00 x 10e-5)=6000000000000
f = v/λ =6000000000000/5.00 x 10e-5=120000000
Explanation:
Ionization energy, also called ionization potential, in chemistry, the amount of energy required to remove an electron from an isolated atom or molecule.
Each of the organic compounds mentioned has a general formula so that we can identify the classification of a certain substance. The compound CH₃CH₂OH is an alcohol because it follows the general formula R-OH, where R is a hydrocarbon chain. In this case, the hydrocarbon chain is ethane. When a hydroxyl functional group is attached, it becomes an alcohol whose name is ethanol.
