Octasulfur(Sg) is the most common allotrope of sulfur and is widely used in the chemical industry, especially in the production of petroleum. While Sg is the main component of elemental sulfur on earth is can also be produced in the laboratory from the reaction of sulfur dioxide with hydrogen sulfide. The balanced chemical equation for this reaction is shown below: 8SO2(g)16H25(g)3S(s)+16H2O (g) Consider the reaction of 93.0 grams of SO2 with 93.0 grams of H2S to answer the questions below....

34) What is the “limiting reagent” in a chemical reaction? Assuming 2 reactants, explain how to calculate/determine the limiting reactant. What is always true and why? 40) Place the following sets of elements in order of increasing size and Explain why they're in that order. [Al, P, Na, Ar], [I, Cl, F, Br] (these are 2 different sets.) 19) Lead and Carbon are in the same column and therefore have the same number of valence electrons. If the electron configuration...

Model 4: Using Moles of Limiting Reagent in Stoichiometry The above pictures are not realistic because they involve so very few molecules. In a "real-world" sample, you are likely to have on the order of 10 molecules. Consider the following: Suppose you have a reaction vessel initially containing 13.5 moles of sulfur dioxide and 11.2 moles of oxygen mol SO, required to react with all O2 = 11.2 mol O2 x 2 mol SO 22.4 mol SO, 1 mol O2...
