Aphoton with a frequency of 5.29x1014 hz has_x10-19 j of energy.

3.505 × 10^-19 Joules

We are given;

Frequency = 5.29 x 10^14 Hz

We are required to calculate the energy of the photon.

Energy of a photon is given by the equation;

E = hf

where, h is the plank's constant, 6.626 × 10^-34 J-s

f is the frequency of the photon.

Therefore,

Energy = 6.626 × 10^-34 J-s × 5.29 x 10^14 Hz

            = 3.505 × 10^-19 Joules

Therefore, the energy of the photon is 3.505 × 10^-19 Joules

the correct answer is b. a strong acid completely dissociates to its ions when dissolved in water. completely dissociates to and ions. a is incorrect because does not fully ionize to and ions and some remain as the compound . c and d are incorrect because, and do not fall into the category of bronsted lowry acids. a bronsted lowry acid is a proton donor and since both molecules do not have a proton to donate they are not bronsted lowry acids. likewise,   if we use the lewis acid definition, they cannot be acids. a lewis acid is an electron pair acceptor. both and have a complete octet so can not accept any electrons which disqualifies them as acids.
