Document Summary

In the blood of an adult human, there are ~2. 60(cid:117)1013 a total of 2. 90 g of iron. A) 1. 83(cid:117)1023: consider the following reaction: wo3(s) + 3 h2(g) (cid:111) w(s) + 3 h2o(g) When 1. 00 g of hydrogen gas react with excess wo3(s), 15. 5 grams of w(s) are produced. What is the percent yield? (the molar mass of w is 183. 84 g/mol. : bf3, 2. 28(cid:117)10 1, 51. 1, 25. 5, 17. 0, 8. 52, phosphoric acid is commercially produced by the three step furnace method : 2 ca3(po4)2(s) + 6 sio2(s) + 10 c(s) (cid:111)(cid:3)4 p(s) + 10 co(g) + 6 casio3(s) 2 : pb2+ and clo4, li+ and oh , ag+ and cl , consider the reaction: 5o2(g) + 4nh3(g) (cid:314) 4no(g) + 6h2o(l) K = 1. 5 103: 2 so3 (cid:3508) 2 so2 + o2. K = 1. 3 10-5: 2 no2 (cid:3508) 2 no + o2.
