Aug 11, 2011 · In the first step of silicon purification, a reaction is brought about between the impure silicon and chlorine. Pure silicon is then used, in the computer industry, for the manufacture of microchips .Si + Cl2 SiCl4 (unbalanced equation) Given that the silicon is 92% pure, calculate the theoretical yield I would really appreciate if you also would tell me how to get to the answer!
(i) Construct a balanced equation for the reaction between propanone and 2,4-dinitrophenylhydrazine. (ii) A similar type of reaction occurs between propanone and hydroxylamine, NH 2OH. Draw the displayed formula of the organic product of this reaction. H 3 C H 3 C CO+ H H NOH  [Total: 6]
