Because many substances can be dissolved in liquids !
To identify these substances a detailed chemical analysis of the residues after evaporation is necessary.
Substances that cannot be dissolved in water are typically nonpolar molecules, such as oil, fats, and wax. In general, substances with strong intermolecular forces that are not easily disrupted by water molecules will not dissolve in water. Examples include hydrophobic molecules like hydrocarbons and certain gases like oxygen and nitrogen.
Yes, liquids can have a smell due to the presence of volatile compounds that evaporate into the air and are detected by our sense of smell. Factors such as temperature, composition, and concentration of the liquid can affect its scent.
If you have salty water for example, and you wish to have just the salt, you must heat the solution. As the solutution heats, the water will evaporate, but the salt will stay, as it cant be evaporated.
no, it proves that x is a compound.
No. When the water evaporates, the sugar reappears, so it underwent a mere physical change.
This claim contradicts the properties and behaviors of chemical substances. It is scientifically impossible for a single liquid to dissolve any substance, as the interactions between molecules and substances are complex and varied. Additionally, there are certain materials that cannot be dissolved by any known liquid.
you cant.
this is the most stupidist qeustion web sit every
it depends which of the 8 seasons it is The lemonade cant evaporate but the water will and the sugarparticles will remain in the bottom The lemonade cant evaporate but the water will and the sugarparticles will remain in the bottom

you know it is dissolved mainly because you cant see it.
if it cant be dissolved it is called insoluble. an example would be Zinc(:
The dissolution of a salt is such a slow process for a couple different reasons. The amount of time dissolution takes is affected by the surface area and rate of solubility, which varies greatly depending on what the salt is dissolving in.
Yes, laundry detergent can evaporate over time, especially if left exposed to air for long periods. The liquid components of the detergent can slowly evaporate, leaving behind a more concentrated form of the detergent. It is best to store laundry detergent in a tightly sealed container to prevent evaporation.
in a liquid hand soap you cant see the different parts so its not a mechanical mixture
No, fecal matter does not completely evaporate. It is a bit like clay. If fecal matter is left in the air, it will dry out and become like hard ground. You can observe this in a cat litter bot. After the cat leaves some, you can find it and watch it in the coming days.The other body waste, urine, will evaporate.
