What concentration of so-is in equilibrium with Ag,SO,(s) and 1.00 x 10-3 M Agt? The Kap of Ag,SO, can be found in this table. [s03-] = The Ksp of cadmium carbonate, CACO3, is 1.0 x 10-2. Calculate the molar solubility, S, of this compound. At 25 °C, only 0.0290 mol of the generic salt AB2 is soluble in 1.00 L of water. What is the Ksp of the salt at 25...

Whenever organic matter is decomposed under oxygen-free (anaerobic) conditions, methane is one of the products. Thus, enormous deposits of natural gas, which is almost entirely methane, exist as a major source of fuel for home and industry. a. It is estimated that known sources of natural gas can produce 5600 EJ of energy (1 EJ = 1018 J). Current total global energy usage is 4.0 x 102 EJ per year. Find the mass (in kg) of known sources of natural...

Saturated, Unsaturated & Supersaturated Solutions Solution, in which the concentration of solute is that determined by its solubility (at given temperature) is called SATURATED solution. One cannot add more solute to such a solution. We also say that a saturated solution is in equilibrium with pure solute: If we add solid Nacl to an already saturated solution of NaCl, that solid remains in equilibrium with dissolved Naci. Solution containing less solute than would be in the saturated solution, is UNSATURATED...

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...
