please answer all the questions
thank you
Acetic anhydride is a clear liquid with a pungent, penetrating, vinegar-like odor. The largest application of acetic anhydride is as a raw material in manufacturing cellulose acetate fibers and plastics. It is also used in the production of aspirin, acetaminophen and other pharmaceuticals manufacturing. In an intermediate step in the production of acetic anhydride, carbon monoxide and carbon dioxide are reacted with hydrogen to make methanol according to the following balanced chemical equations:...
