Only extremely small amounts of silicon dioxide can be dissolved in water, so SiO2 is considered insoluble in water.
I think it might dissolve in water or somthing else
It is the basis of glass and is extremely insoluble in water and most other solvents. HF would be needed to dissolve it.
No. It does not dissolve in water at any temperature.
No, talcum powder does not dissolve in water. Talcum powder is a mineral composed primarily of magnesium, silicon, and oxygen, which does not break down or dissolve in water. Instead, it tends to form a suspension when mixed with water.
The only chemical which effectively dissolves silicon dioxide is hydrofluoric acid. But note that silicon dioxide does dissolve to a very slight extent in water. The beaches are not dissolving away into the ocean, but some tiny amount of silicon dioxide is dissolving.

silicon dioxide is an extended covalent network. Even amorphous SiO2 contains many atoms bonded together. They large covalent networks are too heavy to be maintained in solution by hydrogen bonds with the water.

Sand, or silicon oxide, is fairly inert. It does not dissolve in water. Sand is mostly the same material as glass. So it does not dissolve any faster than glass dissolves in cold water. Hydrofluoric acid is, however, another matter.
Mainly because it's composed primarily of silicon (the same substance as glass), a substance that's insoluble in water.
One way to separate dichlorobenzene from silicon dioxide is to use a solvent extraction method, where dichlorobenzene can dissolve in a solvent like ethanol, while silicon dioxide remains insoluble. After mixing the mixture with ethanol, the solution can be filtered to separate the solid silicon dioxide from the solvent containing dichlorobenzene. The solvent can then be evaporated to isolate the pure dichlorobenzene.
Silicon will sink in water because it has a higher density than water.
No, silicon cannot float on water because it has a higher density than water. When placed in water, silicon will sink.
