metis antibi hang on 11 Asaturated solution of an unknown salt has a density of 1.82 g/mL (1.00 g H:0, 0.82 g solute) at a resist temperature of 50°C. When the solution is cooled to 25°C, some of the unknown salt crystallizes out and Sofia the saturated solution at 25°C has a density of 1.40 g/mL. (Assume that the density of pure water remains constant at 1.00g/mL through this temperature range and the volume of the solutions do not change...

A 40-gallon barrel is filled completely with pure water. Salt water with a concentration of 0.3 lb/gal is then pumped into the barrel, and the resulting mixture overflows at the same rate. The amount of salt in the barrel at time t is given by Q(t) = 12(1 − e−0.07t) where t is measured in minutes and Q(t) is measured in pounds. (a) How much salt is in the barrel after 5 min?

Part a please
Question 3 (30 pts) Lead nitrate (Pb(NO3)2) is a toxic compound used in lead paints in the past. It has far less use now, in specialized applications such as gold extraction. Unlike most lead salts, lead nitrate is soluble in water, as seen below in the solubility chart. After aqueous gold recovery, it is desired to recover the lead nitrate from the water via crystallization. A 70°C aqueous lead nitrate solution containing 50 wt% lead nitrate and...
