Be sure to answer all parts. Industrially, vanadium metal, which is used in steel alloys, can be obtained by reacting vanadium(V) oxide with calcium at high temperatures: 5Ca + V₂05→ 5CaO + 2V In one process, 1.540 × 10³ g of V₂O5 react with 2.080 × 10³ g Ca. (a) Calculate the theoretical yield of V. (b) Calculate the percent yield if 811.0 g of V are obtained. % Report your answers to the correct number of significant figures.
