You can look at your notes, the book, and D2L content to help do these problems as well as
discuss with your peers, and your instructor. You may not use internet sources or post any
of this on sites like Chegg or StuDocU. Doing so is an academic integrity violation. We
recommend you try this problem in an exam-like approach using just your calculator, a
periodic table and some paper. Only once you’ve tried it, go back and check your notes and
the book. Scan your answers and submit as one file.
1. Two solutions are combined: 240.0 mL of 0.100 M AgNO3(aq) and 145.0 mL of 0.125 M of MgCl2(aq). These react according to the following molecular equation:
2 AgNO3(aq) + MgCl2(aq) 2 AgCl(s) + Mg(NO3)2(aq)
Clearly answer the following questions: a) Which species is the limiting reagent? b) How many grams of AgCl(s) gets formed? c) What are the spectator ions in the reaction? d) What are the final concentrations of all ions in solution? e) If 2.85 g of AgCl are isolated, what is the percent yield?
