What is the mole ratio of the reacting species (reactants) when the above equation is balanced? Whalley CL(1), Martín JC, Wright TG, Plane JM. The Heat of Reaction (also known and Enthalpy of Reaction) is the change in the enthalpy of a chemical reaction that occurs at a constant pressure. these need 1.440 / 3 moles of N2 for a complete reaction = 0.480 moles but we have 15g / 28.0134 g/ moles of N2 = 0.535 moles so the N2 is in excess and the yield limiting reagent is Mg according to the equation we will get 0.480 moles of Mg3N2 NaOH(aq) + HCl(aq) H NaCl(aq) + H2O(l) Ionic ... Li K Ba Ca Na Mg Al Zn Fe Cd Ni Sn Pb (H) Cu Hg Ag Au Most reactive Least reactive SOLUBILITY RULES ION RULES Group IA 1. Mg + N2 -----> Mg3N2. Liberation of a gas during the initial reaction in system (A) and the fact that complexes [C_+H,FeCI&THF),Mg 6H,OJ (IV) and [(C,H,),FeCl,(THF),Mg, 6H,O] (V) differ from one another in terms of a C4HSMg(THF),CI, group indicate that a Grignard compound is formed in the system MeCl, + THF + N2.
