This aromatic synthesis uses reaction of a diazonium salt as a key step. The transformation occurs in 5 steps and involves the following reactions: (1) nitration, (2) reduction, (3) diazotization, (4) Sandmeyer, (5) reduction.

Answer charle's law

Rate law for this reaction israte of the reaction = k[a]²[b].second order in a  means concentration of a in power of two, and  first order in b means concentration of b in power of one.

The population of unionid mussels decreased after zebra mussels were introduced. zebra mussels competed with the unionid mussels for food. the zebra mussels were able to displace the unionid mussels, allowing the zebra mussel population to increase  over the years. the unionid mussel population decreased because  of lack of food.
