Don’t currently have a calculator with me but just use Avogadros constant (A) 6.02x10^24, in the equation n=N/A. Lower case n being the number of mol and upper case being the number of molecules (given).
Answer:
4.5 × 10^14 Hz
Explanation:
According to this question, chlorophyll pigment strongly absorbs light with a wavelength of 662nm. To calculate the frequency of this light, the following formula is used:
λ = v/f
Where;
λ = wavelength (m)
v = speed of light (3×10^8m/s)
f = frequency of light (Hz)
Since the λ = 662nm = 662 × 10^-9m,
f = v/λ
f = 3 × 10^8/662 × 10^-9
f = 0.004531 × 10^(8+9)
f = 0.0045 × 10^17
f = 4.5 × 10^14 Hz

Conduction is heat tranfer through physical contact. Hope this helps. :)
This question is making an appeal to your logic.
Definitions
The hump between A + B and C + D is the activation energy.
The forward activation energy is going from a low of 40 up to a high of 100.
The backward activation energy is going from a low of 20 and a high of 100.
Answer A
Look at the curve. which is higher, 40 or 20? You pick the one that is higher? A must be true.
Answer B
If A is true, B cannot be.
Answer C
C can't be true. Again the diagram holds the answer. The hump starts higher on the side of A+B. It takes less energy to get over the hump on the A+B side than the C + D side.
Answer D
The activation energies are not the same.
