Calculate the number of molecules present in 0.750 mol of mgo.

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?

How many moles of co2 are produced during the complete combustion of 3.6 moles of c2h6
