QUESTION 3 Salicylic acid reacts with acetic anhydride to form aspirin and acetic acid as shown. Use the equation to answer Questions 3 – 6. (salicylic acid) (aspirin) C7H6O3 (s) + C4H6O3 (l) → C9H8O4 (s) + CH3COOH (l) MM = 138 MM = 180 If we divide 180 by 138 we find that 1.00 g salicylic acid will produce a maximum of 1.30 g aspirin. 3. A student starts with 3.20 g salicylic acid. What is the maximum amount...

In an Amide Synthesis reaction between acetic anhydride & an unknown primary amine with aluminum oxide. "1. Why is it essential that no water or alcohols are present during the amide synthesis reaction you performed in lab this week? Acetic anhydride can be quenched simply by washing the reaction mixture with water. Provide the balanced equation for the reaction of acetic anhydride and water below."
Aspirin can be synthesized in the lab by combining salicylic acid (C7H6O3) and acetic anhydride (C4H6O3) to form aspirin (C9H8O4) and acetic acid (C2H4O2).C2H4O2). The balanced equation for this reaction is C7H6O3+C4H6O3⟶C9H8O4+C2H4O2 A student started with 4.00 mL acetic anhydride (density=1.08 g/mL) and 2.07 g salicylic acid. The student synthesized 2.00 g of aspirin. Select the limiting reactant. acetic acid (C2H4O2) salicylic acid (C7H6O3) aspirin (C9H8O4) acetic anhydride (C4H6O3) Calculate the theoretical yield of aspirin (C9H8O4). theoretical yield: Calculate the...
Aspirin can be made in the laboratory by reacting acetic anhydride (C4H6O3) with salicylic acid (C7H6O3) to form aspirin (C9H8O4) and acetic acid (C2H4O2). The balanced equation is C4H6O3+C7H6O3→C9H8O4+C2H4O2.In a laboratory synthesis, a student begins with 2.90 mL of acetic anhydride (density=1.08g/ml) and 1.26 g of salicylic acid. Once the reaction is complete, the student collects 1.22 g of aspirin. Determine the theoretical yield of aspirin for the reaction. Determine the percent yield of aspirin for the reaction.
Aspirin can be made in the laboratory by reacting acetic anhydride (C4H6O3) with salicylic acid (C7H6O3) to form aspirin (C9H8O4) and acetic acid (C2H4O2). The balanced equation is C4H6O3+C7H6O3→C9H8O4+C2H4O2 In a laboratory synthesis, a student begins with 3.10 mL of acetic anhydride (density=1.08g/ml) and 1.24 g of salicylic acid. Once the reaction is complete, the student collects 1.21 g of aspirin. Determine the theoretical yield of aspirin for the reaction. And determine the percent yield of aspirin for the reaction.
Aspirin can be sunthesized in the lab by combining salicylic acid (C7H6O3) and acetic anhydride (C4H6O3) to form aspirin (C9H8O4) and acetic acid (C2H4O2). The balanced equation for this reaction is C7H6O3+C4H6O3⟶C9H8O4+C2H4O2 A student started with 4.45 mL acetic anhydride (density=1.08 g/mL) and 2.34 g salicylic acid. The student synthesized 2.47 g of aspirin. Calculate the theoretical yield of aspirin (C9H8O4) in grams Calculate the percent yield for aspirin (C9H8O4)
Aspirin can be made by reacting acetic anhydride (C4H6O3) with salicylic acid (C7H6O3) to form aspirin (C9H8O4). C4H6O3 + C7H6O3 --> C2H4O2 + C9H8O4 When synthesizing aspirin, a student began with 3.05 mL of acetic anhydride (density = 1.08 g/mL) and 1.85 g of salicylic acid. The reaction was allowed to run its course and 1.84 grams of aspirin was collected by the student. Determine the limiting reactant, theoretical yield of aspirin, and percent yield for the reaction.
