Answer:
7.11 x 
Hz
Explanation:
The equation for converting wavelength to frequency is ν=c/λ, or the speed of light over wavelength. The speed of light is 3.00 x 
, and our wavelength here is 422 x 
. All we have to do now is substitute our given values:
After reduction, our answer comes out to be about 7.11 x Hz.
The empirical formula of the compound with the percent composition C 18.1%, H 2.27%, Cl 79.8% is C₂H₃Cl₃.
<h3>What is an empirical formula?</h3>
It is the minimum ratio between the elements that form a compound.
- Step 1: Divide each percentage by the molar mass of the element.
C: 18.1/12.01 = 1.51
H: 2.27/1.01 = 2.25
Cl: 79.8/35.45 = 2.25
- Step 2: Divide all the numbers by the smallest one.
C; 1.51/1.51 = 1
H: 2.25/1.51 ≈ 1.5
Cl: 2.25/1.51 ≈ 1.5
- Step 3: Multiply all the numbers by 2 so all of them are whole.
C: 1 × 2 = 2
H: 1.5 × 2 = 3
Cl: 1.5 × 2 = 3
The empirical formula is C₂H₃Cl₃.
The empirical formula of the compound with the percent composition C 18.1%, H 2.27%, Cl 79.8% is C₂H₃Cl₃.

Answer:
Option C (nuclear binding energy) is the appropriate choice.
Explanation:
- At either the nuclear scale, the nuclear binding energy seems to be the energy needed to remove and replace a structure of the atom itself into the characterize elements (to counteract the intense nuclear arsenal).
- Nuclear warheads (bargaining power) bind everything together neutrons as well as protons within an elementary particle.
Some other options in question aren't relevant to the particular instance. So that the option preceding will also be the right one.
Of which reaction may I ask? And do you mean 1-bromo-2-methylcyclohexane??
Please be specific. Which umbrella?
