The fizz produced when an Alka-Seltzer tablet is dissolved in water is due to the reaction between NaHCO3 and citric acid NaHCO;(aq) + H;C,H;O,(aq) → CO2(g) + H,O(1) + Na,C,H;O,(aq) In a certain experiment 1.00 g of NaHCO3 and 1.00 g of citric acid are allowed to react. Which is the limiting reactant? How many grams of sodium citrate (the last compound in the equation) form?

Aspirin can be synthesized in the lab by combining salicylic acid (C,H,O,) and acetic anhydride (C,H,0,) to form aspirin ( C,H,O,) and acetic acid (C, H, 0,). The balanced equation for this reaction is C,H,O, + C,H,0, C,HgO, + +C,H,O, A student started with 3.49 mL acetic anhydride (density = 1.08 g/mL) and 2.09 g salicylic acid. The student synthesized 2.14 g of aspirin. Select the limiting reactant. acetic anhydride (C,H,O,) acetic acid (C,H,O,) O salicylic acid (CH,O,) O aspirin (C,HO,) Calculate the theoretical yield of aspirin (C, HO,). theoretical yield: Calculate the percent yield for aspirin (C,H,O). percent yield:
