One of the main components of hard water is caco3. when hard water evaporates, some of the caco3 is left behind as a white mineral deposit. plumbing fixtures in homes with hard water often acquire these deposits over time. toilets, for example, may develop these deposits at the water line as the water in the toilet slowly evaporates away. if water is saturated with caco3, how much of it has to evaporate to deposit 0.390 g of caco3? ksp for caco3 = 4.96 x 10-9.

Hannah is writing a report on how albedo affects the global climate. she’s proofreading her passage for any factual errors. which sentence must hannah correct before submitting her report? earth receives energy from the sun. this energy drives many of the processes on earth, including its climate. some part of this energy is reflected by earth’s surface. we use the term albedo to describe the reflected energy. albedo of an object is the ratio of the reflected radiation to the total radiation reaching the object. a value of 0 means no energy is absorbed by the object, whereas a value of 1 means that all of the energy is absorbed. in this way, the albedo of an object can influence earth’s atmospheric temperature.
