Answer:
Increases, remain constant
Explanation:
In the light spectrum, the photons with a higher frequency (hence smaller wavelengths) have higher energy. The lower the energy the lower the frequency and longer the wavelengths. The intensity of light does not change the energy levels of these photons. The higher the intensity the higher the density of the photoelectrons.
<u>Answer:</u> The molarity of
ions in the solution is 0.306 M
<u>Explanation:</u>
To calculate the molarity of solution, we use the equation:

We are given:
Mass of solute
= 15.6 g
Molar mass of
= 295.6 g/mol
Volume of solution = 345 mL
Putting values in above equation, we get:

As, 1 mole of
produces 1 mole of copper (II) ions and 2 moles of nitrate ions.
So, molarity of
ions = (2 × 0.153) = 0.306 M
Hence, the molarity of
ions in the solution is 0.306 M
