Explanation: The relation of Planck's constant relating the Joules of energy absorbed/released by matter is usually used to determine the energy of the photon. The mathematical expression is -
E= h c /
Thus as we can observe that the energy is directly proportional to the speed of light and inversely proportional to the wavelength of the light.
Thus , we can say that Planck's constant relates the Joules of energy absorbed/released by matter to the observed wavelength of light.
The right answer for the question that is being asked and shown above is that: "B. observed wavelength of light" Planck's constant relates the Joules of energy absorbed/released by matter to the <span>B. observed wavelength of light</span>
I think you want to ask the complete ionic equation and net ionic equation. For complete ionic equation: 3Ba2+ + 6Cl- + 2Al3+ + 3SO42- -->3BaSO4 + 2Al3+ + 6Cl-. For net ionic equation: 3Ba2+ + 3SO42- -->3BaSO4.
