The solubility of a substance is 12.0 g per 100. g of water at 20.0°C. It is 18.0 g per 100. g of water at 60.0°C. How many grams of the substance can crystallize from a saturated solution that contains 200.g
of water at 60.0C if the solution is cooled to 20.0°C?

in 1783 cavendish was working with his hydrogen gas and found that when he burned it and condensed the vapor it was water. this was very significant since it disproved the greek theory of elements completely since water was not a simple substance but the product of two gases. it was lavoisier who hearing of the experiment gave cavendish's gas the name hydrogen ("water-producer") and added that hydrogen burned by combining with oxygen and that water was a hydrogen-oxygen combination.

by the combination of an unlimited number of elements

hurricanes form when warm, moist air from the ocean surface quickly rises into the atmosphere and forms storm clouds and rain. when the clouds are formed, heat is released which warms the cool air in the upper regions of the atmosphere so that the cycle can continue. which two phases of the water cycle are repeated in this process?
