Answer:First: the coefficients give the number of molecules (or atoms) involved in the reaction. In the example reaction, two molecules of hydrogen react with one molecule of oxygen and produce two molecules of water. Second: the coefficients give the number of moles of each substance involved in the reaction.

The n=2 --> n=1 transition in the hydrogen atom has the shortest wavelength. In addition, microwave has a highest frequency wave. In finding the limiting reagent, grams divided by the molar mass and the answer will be divided by the coefficients and the lowest amount is the limiting reagent.
It is neither, it is a pure substance.
