Answer:
D, potassium hydroxide
Explanation:
Nitric acid us given and is obviously an acid
Answer:
2 eV
Explanation:
The energy of a photon of light is given by the formula

where
h is the Planck constant
c is the speed of light
is the wavelength of the photon
In this problem we have:


is the wavelength of the photon
Therefore, the energy in Joules is

We want to convert this energy into electronvolts: we know that the conversion factor is

Therefore,
