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...

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...
I'll be thankful for your help ?? Example: HW When aqueous solutions of silver nitrate and potassium dichromate are mixed, an exchange reaction occurs, and silver dichromate is obtained as a red solid. The overall chemical equation for the reaction is as follows: 2AgNO3(aq)+K2Cr2O3(aq)-Ag,Cr,0,($)+2KNO3(aq) What mass of Ag2Cr207 is formed when 500 mL of 0.17 M K2Cr207 are mixed with 250 mL of 0.57 M AgNO3? Hint: • Calculate No. of moles of both reactants from given Molarity and Volumes...
