In the experiment, the student reacts 2.500 g of nickel (II) chloride hexahydrate (molar mass = 237.6878 g/mol) with 4.000 g of ethylenediamine (molar mass = 60.0992 g/mol). After isolating the product, the student collects 3.200 g of the nickel coordination compound. NICI2•6H2O (aq) + 3H2NCH2CH2NH2 (1) → [Ni(H2NCH2CH2NH2)3]Cl2 (s) + 6H2O (1) What is the limiting reactant in the reaction above? In this reaction, the limiting reactant is... O ethylenediamine O nickel (II) chloride hexahydrate O This reaction is stoichiometric, so there is no limiting reactant.
