A scientist has 38.5 moles of chlorine and an unlimited supply of both sodium and beryllium. Determine the maximum mass of the fictional compound Na4Be5Cl7 that can be created.

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?
