Answer #1

Sb4 + 6 Cl2 ---> 4SbCl3

Moles of Sb4 = 4.50/487.2 => 0. 00924 mol

Moles of Cl2 = 3.25/71 => 0.0458 mol

a) Cl2 is limiting reagent.

b) mass of SbCl3 = 228.15×4×3.25/6×71 => 6.96 g

c) % yield = 4.85×100/6.96

=>69.7 %

    When ethane, C2H6, reacts with chlorine, Cl2, the main product is C2H5Cl, but other products containing Cl such as C2H4Cl2 are also obtained in small quantities. C2H6 + Cl2 C2H5Cl + "Other Stuff" The formation of these other products reduces the yield of C2H5Cl. Using the stoichiometry given in the chemical formula above, calculate the percent yield of C2H5Cl if the reaction of 150 g of C2H6 with 230. g of Cl2 produced 170 g of C2H5Cl.
