<u>Answer:</u> The longest wavelength of light is 656.5 nm
<u>Explanation:</u>
For the longest wavelength, the transition should be from n to n+1, where: n = lower energy level
To calculate the wavelength of light, we use Rydberg's Equation:
Where,
= Wavelength of radiation
= Rydberg's Constant =
= Higher energy level =
= Lower energy level = 2 (Balmer series)
Putting the values in above equation, we get:
Converting this into nanometers, we use the conversion factor:
So,
Hence, the longest wavelength of light is 656.5 nm
You would need exactly 50 molecules of glucose.
Answer:
The more substituted alkene will be the major product.
Explanation:
D=m/v. (Density equals mass over volume).
So in your case density = 4.2/6
Which equals 0.7
Your units will be grams over milliliters
So your answer is 0.7 g/ml
