Important information about 4 questions (L5)What is the main structural feature of the azo dyes that causes them to be colored compounds?
Methyl Orange is an acid-base indicator. In dilute solution at pH greater than 4.4, it is yellow.At pH = 3.2 the solution appears red. Draw a structure of the species that is formed at the lower pH of the acid proton adds to the azo nitrogen atom adjacent to the aromatic ring containing the -SO3 group. Why does the proton add to this particular nitrogen when two other nitrogen atoms are available in the molecule?
In the formation of diacetylferrocene, the product is always the one in which each ring is monoacetylated. Why is no diacetylferrocene produced in which both acetyl groups are on the same aromatic ring?
Ferrocene cannot be nitrated using the conventional HNO3-HzSO4 mixed acid conditions, even though nitration is an electrophilic aromaticsubstitution reaction. Explain.
Table salt and sugar are accidentally mixed A 4.90 g sample is burned and 2.20-g of CO2 is produced What is the mass percentage of salt in the mixture?

At room temperature (about 20degree C) milk turms sour in about 64 hours. In a refrigerator at 3 degree C, milk can be stored for about three times as long before turning sour.
determine the mass of silver phosphate formed when 4.33 g of silver nitrate is reacted with 22.7 mL of .118 M K3PO4 ?
construct an energy level diagram (molecular orbital) for the molecule SO. We are then asked to comment on the ionic species of SO - bond order, bond distance etc. So far so good.
