0.1 Maq, solution of roseocobaltic chloride [COCI,.5NH, H, O] shows osmotic pressure 4 times greater than urea solution having same strength Assuming complete ionisation of the complex, the number AgCl moles obtained during reaction of given compound with excess AgNO3, (1) 0 ( (2) 1 (3) 2 (4) 3

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.)
