in this stoichiometry problem, determine the theoretical yield:

excess aqueous copper(ii) nitrate reacts with aqueous sodium sulfide to produce aqueous sodium nitrate and copper(ii) sulfide as a precipitate. in this reaction 469 grams of copper(ii) nitrate were combined with 156 grams of sodium sulfide to produce 272 grams of sodium nitrate.

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.
