A student set up an experiment for six different trials of the reaction between 1.00-M aqueous acetic acid, CH3COOH, and solid sodium hydrogen carbonate, NaHCO3. CH3COOH(aq) + NaHCO3(s) NaCH3CO2(aq) + CO2(g) + H2O() The volume of acetic acid was kept constant, but the mass of sodium bicarbonate increased with each trial. The results of the tests are shown in the figure. (a) In which trial(s) is the acetic acid the limiting reactant? (b) In which trial(s) is sodium bicarbonate the limiting reactant? (c) Explain your reasoning in parts (a) and (b).

Constants Periodic Table Hydrates are solid compounds that contain water molecules. When hydrates are heated, the water molecules evaporate, producing the anhydrous form of the compound. The formula of a hydrate may be written in two different ways. For example, aluminum chloride hexahydrate can be written as (Al(H2O)6]Cl3 or as AlCls 6H2O. The first formula more accurately shows the bonding arrangement, whereas the second formula makes it easier to see that the anhydrous form of the compound is aluminum chloride. Part B IF 12.0 g of MgSO4 - 7H2O is thoroughly heated, what mass of anhydrous magnesium sulfate will remain?
