Arower! Fees - Fee S3 The Balanced Reachan is 2Fe + 3s Fe₂ S3 from the Balanced Reachan we get. s 3 More of 2 more of Fe React with to Rodue role of Fe₂S3 (9) Fey S3 So 3 mode of more of Sulphur will produe 2.2 Mole of sulpher will produe 2.2 more of Fes3 Mcle of Fejs = 0.733 more. (b) 2 more of te react with a more of sulphen Produe Imde of Fe, S3 I role of Re Redue mere of resa. so role of ce ince of Fedz 2 more of te= 2x 2.2 mure of F283 wt = 4.4 more. & weigt (9) = 4.4x53.84 4 и se o = 245.696g) I role of Supre mole of Fees mode heren 5 206 207.9 % *** I wist of sulphur = 21:34g 3 41888 X
