three emission line involving three energy levels in an atom occur at wavelength x,1.5 x, and 3.0x nm which wavelength corresponds to the transition from the highest to the lowest of the three energy levels​

If 10.0 ml of the solution on the right are withdrawn from the 100 ml beaker and diluted again in a similar manner, what is the new concentration? m nacl

Does anyone know a lot about how to: - calculate mass of magnesium metal - calculate the actual yield of magnesium oxide - calculate the theoretical yield of mgo - calculate the percent yield of mgo - determine the percent yield of mgo - determine the average percent yield of mgo i had to do an online lab and its asking these questions but i have no idea where to start or how to be able to find these things. i can post the chart of the data from the lab or if you can tell me exactly how i can find each.

Temperature is _related to the average kinetic energy of a gas. inversely directly not disproportionally
