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.
