tin(iv) sulfide, sns2, a yellow pigment, can be produced using the following reaction. snbr4(aq) 2na2s(aq)⟶4nabr(aq) sns2(s) suppose a student adds 45.5 ml of a 0.511 m solution of snbr4 to 53.2 ml of a 0.118 m solution of na2s. identify the limiting reactant. sns2 snbr4 nabr na2s calculate the theoretical yield of sns2. theoretical yield: g the student recovers 0.344 g of sns2. calculate the percent yield of sns2 that the student obtained. percent yield:
