1) When are covalent bonds most likely to form? a. between 2 atoms with a high ionization energy b. between 2 with a low ionization energy. c when one atom high and other low d. no correct choice. (I'm leaning towards a.)
2) When you have a sample of a gas at constant temp and the # of moles are doubled when P is halved, what happens to the V?
Does it increase, decrease or not change? My guess is it increases?
