1) Using equation 1 (1/wavelength = R(1/n1^2 - 1/n2^2), calculate n2 for these three lines:
402.6nm, n2 =
447.1nm, n2 =
587.5 nm, n2=
2) Draw a diagram depicting the electron transitions that occurred to produce these emissions.
3) Explain why your results (2) indicate that the electron behavior of atoms of elements with more than one electron is not well described by equation 1, if Bohr's picture of the atom is correct.
(The molecular formula for X is C8H8O2), and (The empirical formula for X is C4H4O) are all true. C) The empirical formula for X is C4H4O. D) The molecular formula for X is C8H8O2. E) X has a molecular mass of 136.

What is the ph change of a 0.300 M solution of citric acid (pKa=4.77) if citrate is added to a concentration of 0.130 M with no change in volume
why is it best to cool the crucible and lid (and sample) in a desiccator rather than on the laboratory bench
A 100.0 Ml SAMPLE OF 0.100 M methylamine (CH3NH2, Kb = 3.7 x 10^-4) is titrated with 0.250 M HNO3. Calculate the pH after addition of each of the following volumes of acid
At a certain temperature* (probably not 25 ºC), the solubility of silver sulfate, Ag2SO4, is 0.023 mol/L. Calculate its solubility product constant for this temperature.
Positronium consists of an electron and a positron (same mass, opposite charge) orbiting round their common centre of mass. The broad feature of the spectrum are therefore expected to be hydrogen-like, the differences arising largely from the mass..
