Is sandy water a element a compound or mixture?

Answer 1

Sandy water is a mixture. You can tell this because if you boil off the water you will be left with Sand.

The two materials can separate through a physical interaction (Meaning no new substances are formed) showing that it is a mixture instead of a compound.

Water is a compound because though it will not separate through any physical interactions (Boiling, condensing, freezing, melting, being put through a filter etc) It will separate when electricity is run through it forming Hydrogen and Oxygen. (This is a chemical change because new substances are formed that were not there before.)

Answer 2

Sand is a mixture of very small pieces of rocks and minerals that are all different colors and sizes and thus different compounds.

Sand in water is also a mixture: very heterogeously, sand sinks to the bottom, but there is still water between the sand particles.

Water on its own is a pure compound (molecules of one kind) and water molecules (H2O) are made up of two different elements (H and O): 2 atoms hydrogen (H) and one atom oxygen (O), very thightly bonded together.
