Take-Home Assignment This assignment is due on Friday, January 31st. How many grams of FeCl3 could be made by reacting 165 mL of a 0.180 M HCl solution with excess iron? (5) → 2 FeCl3(aq) + 3 H2(g) 2 Fe(s) + 6 HCl(aq) =.165. 15mL IL T1000mL HG/ 0165L HCL .180 moles a moles Feclz 162. 2049 IL T6 moles Hell Imol FeCl3 mass of FeCl3 (g):

Answer 1

2 Fels) + 6 Hel lap) 72 Fecs lag) + 3H₂(g) There are 2 reactants, fe and tel. It is mentioned that fe is in excess. So Hell is the limiting reagent which will be completely ased up in the reaction. Limiting reagent deléemines the amount of products formed So we Compare ratios of Hill to Feels from the balanced chemical equation. 6 moles of Hel yields 2 moles Feelz. 165 ml of 0.480M Hel is used. We have to find out moles of Hel whing nz CV where n=moles; c= Concentention Vevolume in Litres. Convent 165 ml to L.) 1 L=1000 ml. 165 ml = 165 t = 0.1656. 1000

Or 180 M is Concentration and or 165L is volume So, n= 0, 8080,165 =000297 moles Hel is used. If 6 moles Hel yields 2 moles Feelz 0,0297 moles Hel yields ? Feelz 6:2:20.0297:12 2x010297 _ 0.0099 moles Feelz will be made Now Convent moles to mats wling, nam or mi no Mr. where mimats in grams, na moles, Mr = Molecular man Mj of feels is to be found thing atomic marses of Fe and d.

Feelz has 1 Fe alam and 3 d3 alams. Mans of Fe = 55,845 Man of I= 35.4653 (551845X1) + (35.453x3) =5518465+ 106.359 = 162.2014 is My of Feelz. man.Mr = 0.0099 x 162,204 = lobosq. 1.6o5g Feels is made
