1. If an aqueous solution ____ is added to a mixture of Ba^2+ and Fe^3+, the barium ion will precipitate, but the iron ion will remain in solution
answer is Na2SO4
but how and why did they get that answer, I don't understand. Can you please explain to me how they got the answer.
2. Aspirin (C9H8O4) is produced by the reaction of salicylic acid (M=138.1 g/mol) and acetic anhydride (M=102.1 g/mol)
C7H6O3 (s) + C4H6O3 (l) -> C9H8O4 (s) + C2H4O2 (l)
If you mix 2.00 g grams if each reactant, what mass of aspirin (M=180.2 g/mol) can theoretically be obtained?
a. 2.00 g
b. 2.61 g
c. 2.71 g
d. 3.53 g
e. 4.00 g
the answer is 2.61 g, can you please explain how to get this answer, what steps to take etc. I am very confused on how to solve this problem too.
