Adipic acid, C6H10O4, is a raw material for the making of nylon and it can be prepared in the laboratory by the following reaction between cyclohexene, C6H10, and sodium dichromate, Na2Cr2O7 in sulphuric acid. 3 C6H10 + 4 Na2Cr2O7 + 16 H2SO4 >
3 C6H10O4 + 4 Cr2(SO4)3 + 4Na2SO4 + 16 H2O

To prepare 12.5 grams of adipic acid in 68.6% yield requires how many grams of cyclohexen

Mass of Cyclohexen : 10.2 g

Reaction

3 C6H10 + 4 Na2Cr2O7 + 16 H2SO4 >

3 C6H10O4 + 4 Cr2(SO4)3 + 4Na2SO4 + 16 H2O

mol C6H10 : mol C6H10O4 = 3 : 3 = 1 : 1

12.5 grams of C6H10O4 , mol C6H10O4 (MW 146.14 g/mol):

mol C6H10 = mol C6H10O4 = 0.124

mass C6H10 :

african americans demonstrated their newly found freedom by relocating often in search of relatives whom they had been separated from during slavery. others established schools to educate freed people and they built institutions such as churches and political organizations to advocate for their rights.
