You are running the synthesis of ammonia reaction: 3 H2(g) + N2(g) --> 2 NH3(g) You add 15 g N2 and 9.0 g H2 to your reaction flask. Which of the following statements are true? (More than one option may be correct) H2 is the limiting reactant because the limiting reactant calculation showed that less NH3 can be produced from H2 as compared to the amount of NH3 possible from the N2. N2 is the limiting reactant because the limiting...
