When heated, lithium reacts with nitrogen to form lithium nitride: 6Li (s) + N2

Question

When heated, lithium reacts with nitrogen to form lithium nitride: 6Li (s) + N2 (s) ----> 2LiN 9s) If 12.3 g of Li are heated with 33.6 g of N2: a) Determine the limiting reactant b) What is the theoretical yield of the reaction? c) If 5.89 g of Li3N is formed. What is the percent yield of the reaction? please show all work

Explanation / Answer

> 208.2 g of PCl5 are expected to form from 70.91g Cl2 when the % yield is 100%. => when the % yield is 100% , 61.3 g of Cl2 will form 208.2*61.3/70.91 = 179.984 g PCl5 but here 119.3 g of PCl5 is formed. => % yield = 119.3*100/179.984 = 66.284%
