In my chemistry class we use the Rydberg constant for hydrogen. Are there constants for other elements as well? Where can I find these values? Also, as far as I know, the Lyman, Balmer, and Paschen series only concern the hydrogen atom. Are there other series for other atoms, because that would mean there are a lot of series… or is it derived from these series?

jim h asked:


Let’s say one uses 100 kilowatt generating capacity to produce hydrogen from water using electrolysis, and runs the process for one hour. If he then turns around and uses the hydrogen to generate electricity, how much can he generate? Can he then produce 25 kilowatts for one hour? 50 kw? In other words, is the return from electrolysis 25%? Is it 50%? I am interested in the storage capacity from hydrogen produced with renewable energy. Thanks.

i mean we can get clean and cheap energy from water through chemical action by separating hydrogen and oxygen that exist in the water and can use this hydrogen and oxygen in cars and all kind of engines

Scott asked:


When filling a confined space with just hydrogen and oxygen gas, and then igniting the gasses, what is the optimal ratio of hydrogen to oxygen to release the most energy?
Also, what happens if you change the ratio? Do other ratios change the time, temperature, energy, etc. of the explosion?

Karin S asked:


I try to anwser this question and found the formula that describes the energy of each of the quantum states of a hydrogen-like ion. I pretty quess i have to work with this but don’t know exactly how.
E= -13.60 eV / n^2 = -3.40 eV / n^2
And I am also not 100% sure wheter this is the right formula I have developed.
Thanks
