Chemistry Chapter 4 Test WITH QUESTIONS AND WELL VERIFIED ANSWERS [ACTUAL EXAM 100%] ALREADY GRADED A+ REAL EXAM!! REAL EXAM!!! A 12.39 g sample of phosphorus reacts with 42.54 g of chlorine to form only phosphorus trichloride (PCl3). If it is the only product, what mass of PCl3 is formed? - ANSWER -P+3Cl -> PCl3. P 12.39 g P/30.97 S = .4 mol P. Cl 42.54 g/ 35.45 = 1.2 mol Cl. P .4 mol x 1 mol PCl3/ 1 mol P x 132.32 g PCl3/ 1 mol= 54.93g. Cl 1. 2 mol x 1 mol PCl3/ 3 mol Cl x 132.2 g/ 1 mol Cl = 54.93g Determine L.R. and mass of N that can be from 50.0 g N2O4 and 45.0 g N2H4. MM N2O4 = 92.02 g/ mol. MM N2H4 =32.05 g/ mol. N2O4+2N2H4 -
> 3N2+ 4 H2O - ANSWER -L.R. is
