NaHSO 4 (s) + HCl (g) If a manufacturing plant is producing HCl with a percent yield of 82.3%, then how many grams of HCl would be obtained when 34.0 kg of NaCl are reacted with excess H 2 SO 4 ? Chem 110 Recitation Problems – Chapter 4 Part 1 2 3. When iron rusts, iron metal reacts with oxygen gas to produce solid iron (III) oxide according to the following unbalanced equation: Fe (s) + O 2 (g) ! Fe 2 O 3 (s) A. Give the balanced equation. B. Calculate the number of grams of Fe 2 O 3 produced from 15.8 g of Fe assuming the reaction goes to completion. C. How many grams of oxygen gas will be needed to complete the reaction in b? D. If only 14.5 grams of Fe 2 O 3 are produced, what is the percent yield for this reaction? E. If 15.8 g of Fe and 5.00 g of O 2 are reacted, which is the limiting reagent?...
