In fireworks, the heat of the reaction of an oxidizing agent, such as KCIO4, with an organic compound excites certain salts, which emit specific colors. Strontium salts have an intense emission at 641 nm. What is the energy (in kJ) of this emission for 3.16 g of the chloride salt of strontium? Assume that all the heat produced is converted to emitted light. Enter to 2 decimal places.

The electron in an (unbound) hydrogen atom (H(g)) is excited from the ground state to the n=3 state.Which of the following statements are true and which are false. 1. it takes less energy to ionize the electron from n=3 than it does from the ground state.2. The wavelength of the light emitted when the electron returns to the ground state from n=3 is the same as the wavelength of light absorbed to go from n=1 to n=3.3. the electron is farther from the nucleus on average in the n=3 state than in the ground state.4. The first excited state corresponds to n=3.5. The wavelength of light emitted when the electron drops from n=3 to n=2 is shorter than the wavelength of light emitted if the electron falls from n=3 to n=1.
