WebIdentify the limiting reactant. NaBr SnS2 SnBr4 Na2S; Question: 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 34.4 mL of a 0.597 M solution of SnBr4 to 45.4 mL of a 0.119 M solution of Na2S. Identify the limiting reactant. NaBr SnS2 SnBr4 Na2S WebThe structures of oximes 23 and 25 were confirmed by X-ray crystallography which showed clear evidence for co-ordination of the tin by the nitrogen. The aldehyde 22 was also converted into the hydrazone 26, loss of a phenyl substituent from the tin not being observed in this case although the double-bond had been reduced in situ.
