The electronic transitions resulting with the electron in the fourth orbit make up the Brackett series of lines in the emission spectrum. Calculate the wavelength of the lowest energy light and the wavelength of the highest energy light belonging to this series.

Imagine you had to physically add electrons, one at a time, to a previously neutral conductor. you add one electron very easily, but the second electron requires more work. in your initial post to the discussion, explain why this is. also, what happens to the work needed to add the third, fourth, fifth, and subsequent electrons

Akg a of 55 m at an of 11 ? . if is at 98 km/h, be ?

The first-order reaction a→2b+c has rate constant 0.538 s−1. if the initial concentration of a is 0.867 mol l−1, what is the half-life of the reaction in seconds? remember to use correct significant figures in your answer (round your answer to the nearest hundredth). do not include units in your response.
