On an island near the equator, the sun's energy causes ocean water to evaporate during the day. In the afternoon, heavy rains fall. This process is repeated during the summer months. What does this example best show? How most water on Earth is in the form of water vapor

How land is the main source of water during the water cycle

How the sun is the main source of energy for the water cycle

How the ocean is large enough that it never runs out of water

Astudent is given a sample of a blue copper sulfate hydrate. he weighs the sample in a dry covered porcelain crucible and got a mass of 23.875 g for the crucible, lid, and sample. the mass of the empty crucible and lid was found earlier to be 22.652 g. he then heats the crucible to expel the water of hydration, keeping the crucible at red heat for 10 minutes with the lid slightly ajar. on colling, he finds the mass of crucible, lid, and contents to be 23.403 g. the sample was changed in the process to very light clue anhydrous cuso4. if there are again 100.0 g of hydrate, how many grams of cuso4 are in it? how many moles of cuso4? (hint: molar mass of cuso4 = 159.6 g / mole. what per cent of the hydrate is cuso4? you may convert the mass of cuso4 to moles.)
