5:23 O13%DE elearning.yu.edu.jo/m O A student was given 2 beakers labeled with numbers 1 and 2, each beaker contains a clear solution. Additionally, he was given two reagent bottles labeled with A and B. Now, he added reagent A to both beakers and he noticed the formation of a precipitate in beaker 2 but not in beaker 1. However, the addition of reagent B to both beakers resulted in the formation of a precipitate in beaker 1 but not in beaker 2. Based on the information, which of the following is correct? a. compound A is the limiting reactant in beaker 1. b. compound B is the limiting reactant in beaker 2. c. compound A is the limiting reactant in beaker 2. d. compound B will be the excess reactant in beaker 1.

Scientists determine the quantity of atmospheric sulfur dioxide (SO, ), a large contributor to acid rain, by an indirect titration. First, a scientist collects a sample of air and reacts it with hydrogen peroxide (H, 0, ) to form a solution of sulfuric acid ( H, SO, ). Then, the amount of H, SO, produced is determined by titration with a sodium hydroxide solution (NaOH) of known concentration. H,O,(aq) + SO,(g)– H, SO,(aq) H, SO, (aq) + 2 NaOH(aq) 2 H, O(1) + Na, SO4(aq) Suppose Lane collects a 608.0 g sample of air that is known to contain SO, and reacts it with excess H,O, . A volume of 17.8 mL of 0.010 M NaOH is required to neutralize the H, SO, produced. Calculate the mass percent of SO, in the air sample. mass percent: % SO2
