The reaction of 100 g of salicylic acid, c7H6O3 with an excess acetic anhydride produces 50g of aspirin (actual yield.) C9H8O4 according to the equations what is the percentage yield? c7H6O3 + C4H6O3 ——> C9H8O4 + C4H4O2

girl imma just put my comment here because i need a couple point okurrttt

answer : one can design an experiment using a liquid and an additive that can be added to the liquid and observe the chemical changes in the reaction species.

one would need a beaker which is filled with a known amount of the liquid in which thermometer is placed to measure the temperature changes; after addition of the additive to the liquid solution one can note down the temperature change and find whether the reaction is endothermic or exothermic in nature. by subtracting the initial temperature value with the final temperature one can find the temperature changes.

various combinations of liquid and additive can be used. liquid in this case can be a known quantity of water and additives can be epsom salt or without epsom salt the experiment can be conducted to notice the changes. water and ice, hydrogen peroxide and dry yeast, vinegar and baking soda,etc.
