Why did the hot water stay on top of the cold water?

why do you think the hot and cold water mixed when the cold water was placed on top of the hot water?

compare the volume, mass, and density of cold and hot water?

also in the picture the one on the left is cold water, the one in the middle is room temperature water, and the one on the right is hot water.

For the following dehydrohalogenation (e2) reaction, draw the zaitsev product(s) resulting from elimination involving c3–c4 (i.e., the carbon atoms depicted with stereobonds). show the product stereochemistry clearly. if there is more than one organic product, both products may be drawn in the same box. ignore elimination involving c3 or c4 and any carbon atom other than c4 or c3.

Silver tarnishes as silver metal reacts with hydrogen sulfide, h2s, in the air. in this reaction, dark silver sulfide, au2s, covers the surface of silver. when silver is polished, this coating of silver sulfide can be removed from the surface. this makes the silver shiny again. enter the coefficients that balance the tarnishing reaction equation. (type 1 for no coefficient.)

Can you me with this i really appreciate it
