3. If you dissolve lead(II) nitrate and potassium iodide in water they will react to form lead(II) iodide and potassium nitrate. This is a double replacement reaction

A. Calculate the grams of lead(II) iodide that can be produced from 2,75 moles of
potassium iodide.

B. Calculate the grams of lead(II) iodide that are produced if.656 g of KNO; are
produced
Pb(NO3)2(aq) + KI (aq) → Pbl (s) + KNO, (aq)

For a research project, a student decided to test the effect of the lead(ii) ion (pb2+) on the ability of salmon eggs to hatch. this ion was obtainable from the water‐soluble salt, lead(ii) nitrate, which the student decided to make by the following reaction. pbo(s) + 2 hno3(aq) → pb(no3)2(aq) + h2o losses of product for various reasons were expected, and a yield of 86.0% was expected. in order to have 5.00 g of product at this yield, how many grams of pbo should be reacted? (assume that sufficient nitric acid, hno3, would be used.)
