to counteract the sourness of the acids. just did this assignment so i know this is correct
Answer:
Number 1. The effective nuclear change of oxygen is greater that of fluorine.
Answer:
The Equilibrium will shift towards the left.
Explanation:
The reaction for the formation of nitric oxide is follows,

Expression for reaction quotient is as follows,
![Q=\frac{[NO]^2}{[N_2][O_2]}](https://tex.z-dn.net/?f=Q%3D%5Cfrac%7B%5BNO%5D%5E2%7D%7B%5BN_2%5D%5BO_2%5D%7D)
Putting the values according to the data given and calculating reaction quotient for the reaction

So, the reaction quotient is 0.16.
and the value of K is 0.01 .
Q>K
Since the value of K is less than Q, therefore the reaction will shift towards left.
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
