Work

2.00 moles of Butane (C4H10)
Enthalpy of combustion of butane -2878kJ/mol
Assume the reaction occurs at 300 degrees Celsius and a constant pressure of 1.00 atm.

How would you calculate the work associated with a combustion reaction?

Re: Chemistry Jokes

Q: Why do chemists enjoy working with ammonia? A: Because it's pretty basic stuff. A proton and a neutron are walking down the street. The proton says, "Wait, I dropped an electron help me look for it." The neutron says "Are you sure?" The proton replies "I'm positive."
