There exists at least one (actually, a lot more than one) powder that dissolves in water. However, not every powder dissolves in water. It wasn't clear which of the two you were trying to ask.
no. mixtures are homogeneous and heterogeneous. homogenious such as water and sugar which dissolve equally heterogenious such as cookies
It depends on the powders and the liquids. Not all powders are soluable in water but some are soluable in other liquids (like hydrochloric acid).
No a lot of solids do too.
no ot all
Yes. All oxides dissolve in water..
No. Ionic bonds dissolve in water the best.
Na2CrO4 will dissolve in water as will all sodium compounds.
Absolutely not! Using gasoline as a solvent, wax dissolves in it but glass will not dissolve at all. Using water as a solvent, salt dissolves in it but pepper will not dissolve at all. Using hydrofluoric acid as a solvent, glass dissolves in it but wax will not dissolve at all.
CH3OH is the chemical formula for methanol. Methanol is miscible with water in ALL proportions. It DOES dissolve or mix with water.
Powders like sugar, salt, baking soda, etc.

oil does not dissolve at all in water.
Not all solids will dissolve in water at all. Those that do dissolve do so at different rates, and it's also temperature-dependent.

no
All 3 are water based, and crayons are based on wax, which does not dissolve in water.
No, not at all
solutions are not mixtures they are different. a solution is when one of the components e.g salt dissolve into another e.g water. mixture is when the pepper and water are mixed but don't dissolve. so they are different but they just get confused to be the same.
