A mixture of NaCl and NaBr weighing 3.5084 g was dissolved and treated with enough AgNO3 to precipitate all of the chloride and bromide as AgCl and AgBr. The precipitate was treated with KCN to solubilize the silver, and the resulting solution was electrolyzed. The equations are: NaCl + AgNO3 = AgCl + NaNO3 NaBr + AgNO3 = AgBr + NaNO3 AgCl + KCN = KAg(CN)2 + KClAgBr + KCN = KAg(CN)₂ + KBr KAg(CN)2 + 4 KOH = Ag + KCN + Oz + 2 H2O 5028 g. What was the composition of the initial mixture? Atomic masses: Ag-107.87, Na-23,Cl- 35.45, Br-79.9, K-39.1. A mill produces wet paper containing 15% water by weight (wet basis). This water paper is fed in a continuous steady-state operation through a drier where the water content is reduced to 6% by weight. If the heating cost is 5 centavos for every pound of water removed from the paper in the drying operation, what is the heating cost per 100 lb of wet paper fed into the dryer?
