The population census of a city shows that its population has grown in the last decade. This growth has surpassed the city’s ability to provide sufficient water to its people. The city is located about 10 miles from the ocean and has a dry climate. Based on your research and the list of criteria and constraints from part A, suggest a technology to use in this city. Defend your choice with a valid explanation.

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.)
