Energy of Hydrogen-like atoms using Shcordinger's formula
Hello,
Really need help for an homework, here is what I need to do:
For Hydrogen-like atoms, using Schrodinger's formula: Eψnlm=-(h²/2m)d²Eψnlm/dr²+VEψnlm (where V=-ke²/r)
a) Derive a formula for E=1,0,0 , E=2,0,0 and E=3,0,0 (where E=n,l,m) and show the second derivative for each wave function.
b) Calculate the value for each in Joules.
[size=medium]Please advise on how to do this. I

Find the molecular formula of the unknown gas
Hello, this question has been giving me a lot of trouble for quite some time.
I will just outline the details of the question here:
You have a 10 L sample of an unknown gas at STP which undergoes combustion in the presence of excess oxygen. The products were then isolated and cooled at STP. The products were Carbon Dioxide (20 L of gas) and Water (16 g of liquid). What is the molecular formula?

Average Empirical Formula
Hi everyone. I'm taking a Gen Chem class, and I don't know how to solve this problem. I already have calculated all the values I need, but I don't really understand how to use these values to determine the answer to this. Can someone please walk me through this last problem? Thank you.
