The Ostwald process is used commercially to produce nitric acid, which is, in turn, used in many modern chemical processes. In the first step of the Ostwald process, ammonia is reacted with oxygen gas to produce nitric oxide and water. What is the maximum mass of H2O that can be produced by combining 78.0 g of each reactant?

4NH3(g) + 5O2(g) —–> 4NO(g) +6H2O(g)

  • 4 NH3 + 5 O2 → 4 NO + 6 H2O

    (78.0 g NH3) / (17.03056 g NH3/mol) = 4.5800 mol NH3

    (78.0 g O2) / (31.99886 g O2/mol) = 2.4376 mol O2

    4.5800 moles of NH3 would react completely with 4.5800 x (5/4) = 5.725 moles of O2, but there is not that much O2 present, so O2 is the limiting reactant.

    (2.4376 mol O2) x (6/5) x (18.01532 g H2O/mol) = 52.7 g H2O

  • right here is Piaget’s (sought after psychologist) dialectic: he concept-approximately gaining expertise of as being the interaction of subjects with products. once you talk on the subject of the international, you do not talk on the subject of the international. You talk approximately your dating in the direction of that international (that’s Piaget’s dialectic). extra suitable nevertheless, the belief is reflexive: once I talk approximately you speaking on the subject of the international, I talk approximately my dating in the direction of you who talk on the subject of the international. If i intend to make it even crazier, i can borrow an thought from Freitag. Language is a type of historical past following which each little thing is clever… in an extremely elementary experience, my thought relies upon on my interpretation of the international (because of the fact my life is symbolically mediated, my journey of the international is specific by the bounds of the symbols i exploit to characterize that very same international to me). And that concept is additionally reflexively utilized because of the fact i ought to apply symbols to describe the above. EDIT Is each little thing debatable. definite — and ironically, even this answer is.
