Aspirin (c9h8o4) may be synthesized by mixing salicylic acid (c7h6o3) with excess acetic anhydride (c4h6o3).
the balanced equation is c7h6o3 + c4h6o3 c9h8o4 + c2h4o2 when 2.0 g of salicylic acid is mixed with excess acetic anhydride, 1.7 g of aspirin is collected.

what is the percent yield for this reaction?

Astudent made the lewis dot diagram of a compound shown. what is the error in the lewis dot diagram? a)an o atom should transfer all of its six electrons to mg because the formula is mgo b) both electrons of mg should be transferred to one o adam because the formula is mgo c) the electrons should be transferred from each o add him to capital mg because mg has fewer electrons d) the number of dots around mg should be four because it has to transfer two electrons to each o
