Determine the mass of precipitate, in grams, that forms when 62.8 mL of 0.0499 M Pb(NO3)2 reacts with 84.2 mL of 0.0446 M KI. Pb(NO3)2(aq) + 2KI(aq) → 2KNO3(aq) + PbI2(s)

Water's surface tension and heat storage capacity are accounted for by its a) orbitals b) weight c) hydrogen bonds d) mass e) size

Fossil fuels are organic compounds that are made from

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.)
