0.342 x ) photons are required to emit 1 joule of energy.
<h3>What is a photon?</h3>
A photon is a particle of light defined as a discrete bundle (or quantum) of electromagnetic (or light) energy.
We need to find the number of photons emitted per second.
So we have E = hc ÷ λ
= (6.6 x x 3 x m/s) ÷ 6.78 x nm
= 2.92 x Joules
Now number of photons per second = I / E (I = intensity)
= 1 x joule / sec ÷ 2.92 x joule
= 0.342 x
Hence, 0.342 x ) photons are required to emit 1 joule of energy.

PH + pOH = 14
pH = 14 - pOH = 14 - 2 = 12
A pOH of 2 is equivalent to a pH of 12. A pH greater than 7 is basic, and 12 is greater than 7. Therefore, a solution with a pOH of 2 is basic.
Thus, the correct answer choice is B.
