n=2 l=2 ml=-1 ms=1/2

I understand the 2 is the period it is in. Please explain how can find the rest, including how to find which orbital, and it's number?

Thanks

So I put an ice cube in my 1 gallon vacuum chamber and pumped it down to about .3 torr, then shut off the pump and closed the valve. The triple point is about 4.3 torr. I was expecting the ice to sublimate directly into vapor. Why did it melt into liquid instead?

Hi,

I need to find what temperature ice will sublimate at various pressures between 0 and 10 torr. How can I do this?

if 6.38 grams of ethylene glycol burns in Oxygen to produce 9.06 grams of CO2 and 5.58 grams of water vapr. Determine the molecular formula if the Molecular weight is 62 grams/mol.

How can I use this info to determine the answer empirically?

52.4 grams of iron wire burning in 24.7 grams of Oxygen gas? In the lab, if I had a 92.3% yield, what mass of iron (III) oxide would I have recovered?

also,

If .0300 moles of carbon disulfide gas reacts with 62.7 grams of chlorine gas, how many grams of Carbon tetrachloride gas can be made? The other product is disulfur dichloride gas.

Help will be appreciated, thanks :)
