Some substances are soluble. This means they are able to dissolve into other substances. Sugar, for example, is soluble in water, however, vegetable oil is not. This has to do with their chemical makeup.
If the compounds are liquids, here is what determines water solubility: Water molucules have polarity. The solubility of a liquid is determined by its polarity. Polar substances often contain OH-, SH- and NH2- groups. The more of these groups a liquid contains, the more water-soluble it is. These groups can form hydrogen bonds with water, which are very strong. Because these bonds are very strong a molecule that contains more OH-, SH- and NH2- groups is more water-soluble. If the compound is a gas, Henry's Law determines the solubility of gasses in water. This law links the partial pressure of a gas to its mole-fraction in the liquid phase, and thus declares how much of the gas is dissolved. According to calculations from Henry's Law oxygen is more water-soluble than nitrogen.
Henry's Law describes as follows:
P = H * x
In which p is the partial pressure of a gas, H is a constant that differs for each gas and x is the mole-fraction of the gas in the liquid phase.
Some gasses have a specific way of acting when they are dissolved.
Water is slightly polar, which means that one part of the molecule (the O part) is slightly negatively charged, and the other part (the H part) is slightly positively charged. Since opposite charges attract each other, water can pull apart other ionic or polar compounds or ions which also have charges by having the positive parts of them move toward the O of the water and the negative parts of them move toward the H, or by the water molecule slipping inside and separating these charged parts of the compounds or ions. This dissolves them, merely by separating parts of the compounds so that big groups of their molecules or atoms aren't together anymore. An example of this is table salt, sodium chloride (NaCl). The sodium part (Na) is positive, and will be surrounded by the O's of water, and the Chlorine part (Cl) is negative, and will be surrounded by the H's of water. Separating the Na's from the Cl's makes salt dissolve in water. Other compounds and molecules are not polar or ionic. Since they don't have polar charges on them, the slight charges from the water don't pull them apart, and they don't dissolve in water.
help plz a scienceproject problem hurry help
Substances that are polar are soluble while substances that are non-polar are insoluble
because the solvent temperatures are different
because some things do not have the substance to dissolve. while others can. Such as, A lifesaver, it can disolve but a piece of meat cannot.
Water is called a solvent, because of the many things that dissolve in it.
Carbohydrates do dissolve in water such as salt and sugar but their are other carbs that dont dissovle in water such as cabbages,cellulose, and fructose.
maybe in some boiling water, if not then try just regular room temperature water. other than that, i dont know.
Water is a solvent, because some solids will dissolve in it.
No glue that I know of can dissolve chalk.
Water does not dissolve everything. Some substances dont mix with water. Those are hydrophobic substances, ex: oil molecules

Some things that dissolve in water are sugar, soda, food coloring, chocolate syrup, and food particles. Other things that dissolve is salt, vinegar, coffee powder, and copper sulfate.
dont put water in your ears and dont sawoll the water

No. Ionic bonds dissolve in water the best.
metal and water
No glue that I know of can dissolve chalk.
the substance can disslove in water (h2o) are most POWDER. Additional answer A powder is no more or no less able to dissolve in water than if that substance were NOT a powder. Powdering something does not help to make it soluble, though it might make it dissolve more quickly if it's able to dissolve at all. Some substances that dissolve to some extent are salt, sugar, calciul sulphate, copper chloride - millions of things
