A power plant built on a river uses river water as a coolant. The water is warmed as it is used in heat exchangers within the plant. Should the warm water be immediately cycled back into the river? Why or why not?
The salt cesium bromide is soluble in water. When 8.46 g of CsBr is dissolved in 117.00 g of water, the temperature of the solution decreases from 25.00 to 22.79 °C. Based on this observation, calculate the enthalpy of dissolution of CsBr (in kJ/mol).Assume that the specific heat of the solution is 4.184 J/g °C and that the heat absorbed by the calorimeter is negligible.
Change in H dissolution: _____kJ/mol
Wetlands are able to remove nutrients and chemicals from water as the water flows through the area. A developer is planning to destroy most of the wetlands near a bay. In three to five sentences, explain how destroying the wetlands would impact the bay’s water quality and ecosystem.
