Calorimetric studies show that the reaction is exothermic. 2no2(g) n2o4(g) + 14.1 kcal. based on this information, which one--if any--of the following additional changes would increase the molar concentration at equilibrium of n2o4(g)?

decrease the pressure
increase the temperature
decrease the concentration of no2(g)
stir the reaction mixture
none of the above

Aforce of attraction/repulsion due to the spin of electrons what is this force?

How to convert a density of 0.791g/cm3 to lb/ft3

To find the work done, the force exerted and distance moved are multiplied. a couch is moved twice before you are happy with its placement. the same force was used to move the couch both times. if more work is done the first time it is moved, what do you know about the distance it was moved? a) when more work was done, the couch was moved the same distance. b) when more work was done, the couch was moved less. c) when more work was done, the couch was moved further. d) when more work was done, the couch wasn't moved at all.
