Water is a polar molecule, meaning that the hydrogen end has a negative charge, while the oxygen end has a positive charge. When other polar molecules are exposed to these charges they split apart. In salt the sodium has a positive charge that is attracted to the hydrogen's negative charge, and a the chloride has a negative charge that is attracted to oxygen's positive charge.
Yes, water will dissolve calcium chloride. Calcium chloride is highly soluble in water, so it will readily dissolve and form a clear solution.
One example of a solid that is malleable and does not dissolve in water is gold. Gold is a metal that can be easily shaped without breaking, making it malleable, and it does not react with water, so it does not dissolve in it.
To dissolve sodium sulfate, simply add it to water and stir until it is fully dissolved. Sodium sulfate is highly soluble in water, so it should dissolve easily without the need for additional solvents or heat.
Hexane is a non-polar solvent, so it will not dissolve in water. Kerosene is non-polar so it will dissolve in Hexane.
Hydrophilic means that a substance has an affinity for/attraction to water. It binds with water easily. [It is the opposite of hydrophobic, where a substance has an aversion for water. It forms droplets in water (like oil).]
Yes, simple carbohydrates like glucose and fructose are water-soluble and readily dissolve in water due to their molecular structure. This is because they have hydrophilic (water-attracting) properties, allowing them to form bonds with water molecules.

Hydro means water, phobic means to hate and philic means to love, so hydrophobic are those substances which do not dissolve in water and hydrophilic are those which easily become dissolve in water.

Materials that dissolve in water are typically hydrophilic, meaning they have an affinity for water. They are able to interact with water molecules and form stable solutions. Conversely, hydrophobic materials do not easily dissolve in water and tend to repel it.
Milk is mostly water, which is very polar. Sugar (sucrose) is also a rather polar molecule. So, polar compounds dissolve readily in polar solvents. That is why sugar easily dissolves in milk.
Water is polar, and so is salt (because it's ionic and therefore polar by definition.) So salt dissolves easily in water, because in chemistry, "like dissolves like." Ethanol is non-polar (because it's a hydrocarbon, and they're all non-polar.) So water and ethanol won't dissolve in each other. Nor will ethanol dissolve salt.
Dissolve, yes; activate and reproduce, no. Alcohol is a waste product of yeast, and so it has no benefit to the yeast. Yeast feeds on sugars, so it needs carbohydrates (i.e., flour, sugar, fruit) to achieve the desired results, be they gas production for the leavening of bread, or the production of alcohol.
Salt can dissolve in water because the salt molecules hide between the water molecules so that means it can dissolve but it hasn't dissapeared in the water
