A gas tight vessel is filled with air at 27 degrees C and 1.00 atm. Assuming air to be 79% N and 21% O2 (by vol) calculate... A.) partial pressure of N2
B.) partial pressure of O2

Consider the following reactions. (note: (s) = solid, (l) = liquid, and (g) = gas.) mg(s) + ½o2(g) → mgo(s) + 146 kcal/mole h2(g) + ½o2(g) → h2o(g), δh = -57.82 kcal/mole what type of reaction is represented by the previous two examples?
