37.00 mL of 0.100 M aqueous silver nitrate is added to 10.00 mL of 0.500 M aqueous NaCl. A white precipitate forms, is filtered, washed with water and dried. The yield obtained is 501 mg. Answer the following, showing work where appropriate
a) What is the precipitate (name or formula)?
b) Write the net ionic equation:
c) What is the limiting reactant? Must show supporting calculations.
d) To the nearest %, what is the percentage yield? Must show supporting calculations.
e) What is the name for this type of reaction? (not precipitation)
