Steel containing some vanadium (V) metal is used to make extremely tough tools such as axles, plates, car gears, springs, cutting tools, piston rods and crankshafts. V can be obtained by the following reaction. 5Ca + V205 5CaO +2V A chemist used X mol of Ca and Y mol of VO5 to carry out this reaction. a) What is the limiting reagent (limiting reactant)? b) What is the theoretical yield in g V? X = 4.6 mol Ca, Y = 3.1 mol V05 a) Limiting reagent is: b) Theoretical yield is: 2 3 4 5 1A 1 H 1.008 3 Li 6.94 11 Na 22.99 19 K 39.10 2 2A 4 Be 9.01 12 Mg 24.30 3 3B 38 37 Rb Sr 85.47 87.62 55 56 4 4B 21 20 Ca Se 40.08 44.96 47.88 22 Ti 40 Zr 39 Y 88.91 91.22 57 72 5 SB 23 V 50.94 41 Nb 92.91 73 6 6B 24 Cr 52.00 42 Mo 95.94 74 gV 7 7B 43 Te 98.91 75 (Write the formula without subscripting the number of elements, if needed.
