calcocite is a mineral composed of 79.9 mass % copper and 20.1 mass % sulfur. determine the empirical formula for calcocite.

Explain what happens at the saturation point when adding salt to water at room temperature.

How do temperature and salinity affect deepwater currents? as temperatures and salinity levels of water increase, the water rises to the surface where it creates currents as it moves to colder regions. they create changes in wind direction, moving denser water in the same direction as the wind and causing the deepwater circulation patterns found in the ocean. they equalize the forces on undersea currents caused by the coriolis effect as they replace more dense water with less dense water. they create density differences that cause dense deepwater currents to flow toward the equator where they displace less dense, warmer water above them.

Which states of matter have particles that move independently of one another with very little attraction?
