Enthalpy
Oxygen difluoride is a colorless, very poisonous gas that reacts rapidly with water vapor to produce O2 and HF and heat: OF2+H2O->O2+HF2 (DELTA)H=-318kJ What is the change in internal energy for the reaction of 1 mol OF2? I know I need to use P(DELTA)V=(DELTA)nRT but the temperature is not given. Wh...

How many electrons canthe quantum numbers in an atom? [ENDORSED]
The question is: How many electrons can have the following quantum numbers in an atom?
(a)n=2, l=1
(b)n=4,l=2, ml=-2
(c)n=2
(d) n=3,l=2, ml=+1
Please give me a basic run through of how to solve this problem
