Solutions of sodium thiosulfate are used to dissolve unexposed AgBr ( Ksp= 5.0E-13) in the developing process for black-and-white film. What mass of AgBr can dissolve in 1.00L of 0.500M Na2S2O3?
Compound E was heated with bromine and aqueous sodium hydroxide to give compound F (C7H9N). Compound F was treated with cold sodium nitrite and an excess of hydrochloric acid a colorless gas was evolved, and when the resulting liquid reaction mixt..
One method used to store energy during times of low demand is by pumping water uphill into a reservoir. When energy demand exceeds the output produced by power plants, the water is released, moves downhill, and is converted into electricity by a t..
