How do the causes of surface and deepwater currents differ?

Surface currents are caused by wind; deepwater currents are caused by differences in water density.

Surface currents are caused by the Coriolis effect; deepwater currents are caused by differences in water density.

Surface currents are caused by differences in water salinity; deepwater currents are caused by differences in water temperature.

Surface currents are caused by differences in water density; deepwater currents are caused by wind.

Brainliesttt me asap! the below reaction can be categorized as more than one type of reaction. which reactions are these, and what are the types of reactions?

Write the empirical chemical formula of calcium with a mass percent of 38.8, phosphorus with a mass percent of 20.0, and oxygen with a mass percent of 41.3.

A100 kmol/h stream that is 97 mole% carbon tetrachloride (ccl4) and 3% carbon disulfide (cs2) is to be recovered from the bottom of a distillation column. the feed to the column is 16 mole% cs2 and 84% ccl4, and 2% of the ccl4 entering the column is contained in the overhead stream leaving the top of the column. calculate the mass and mole fractions of ccl4 in the overhead stream, and determine the molar flow rates of ccl4 and cs2 in the overhead and feed streams. 12. mw_ccla- 153.82; mw_cs2-76.14.
