I would say that oceans help regulate weather, gobal warming, and solar radiation, but also depends on the level of carbon dioxide in the atmosphere level. So basically the oceans absorbs heat radiation from the sun and it retains the heat, which then the atmosphere comes in and also helps retain the heat which then releases the heat after sunset into space, regulating weather around the globe, since most of the globe is also covered by oceans and water.
NH3 = water (it is actually a water soluble gas)
C6H14 = CCl4 (C6H14 won't mix with water at all)
Na2S = water (Na2S is a salt. Salts dissolve best in water)
Br2 = CCl4, but it will also dissolve in water.
