Question: Answer the following question given this paragraph: Solutions may be prepared in which a solute concentration exceeds its solubility. Such solutions are said to be supersaturated, and they are interesting examples of nonequilibrium states. For example, the carbonated beverage in an open container that has not yet "gone flat" is supersaturated with carbon dioxide gas; given time, the CO2 concentration will decrease until it reaches its equilibrium value. Q: Solutions that are prepared in which a solute concentration exceeds its solubility are called what? Choices: - solidified - instantiated - mineralized - supersaturated A:
Answer: supersaturated

Question: Answer the following question given this paragraph: The landscape of the Moon - its surface features - is very different from Earth. The lunar landscape is covered by craters caused by asteroid impacts ( Figure below ). The craters are bowl-shaped basins on the Moon's surface. Because the Moon has no water, wind, or weather, the craters remain unchanged. Q: The lunar landscape is covered by craters caused by what? Choices: - earth impacts - volcanoes - water - asteroid impacts A:
Answer:
asteroid impacts
