You may be speaking of hydrolysis, in which a macromolecule is broken down into smaller molecules by the addition of water. Refer to the related links for an illustration.
The chemical reaction is:2 K + 2 H2O = 2 KOH + H2
Yes it is because no chemical reaction occurs during it so it is not chemical.
When water is added to the gas jars in which sulphur was burnt, a chemical reaction occurs. The sulphur dioxide gas produced from burning sulphur reacts with the water to form sulphurous acid (H2SO3). This reaction results in the formation of a colorless solution with acidic properties.
Aluminium hydroxide could be formed
Wine will dissolve in water due to the chemical reaction from the sugar of the grapes. This occurs at the end of the fermentation process.
A chemical reaction
Sodium fizzes in water because it is undergoing a chemical reaction with water to form sodium hydroxide. The result is more stable than either of the original chemicals. When sodium chloride is added to water both of these substances are stable with respect to each other and no reaction occurs that results in a new chemical product.
There is NO chemical reaction at all when you dissolve NaCl into water. Dissolving is NOT chemical but a physical change of state.When however a reaction occurs, the original compound is called (one of) the reactant(s) and the compound(s) formed is (are) the product(s) of a chemical reaction.
The chemical reaction is:2 K + 2 H2O = 2 KOH + H2
Hydrolysis is a chemical reaction. Molecules of water are split into hydrogen cations and hydroxide anions in the process of a chemical mechanism.
Yes it is because no chemical reaction occurs during it so it is not chemical.
Hydration
You think probable to an exothermic reaction.
There is no chemical reaction between isopropanol and water, they simply mix.
Carbon dioxide + Water = Gluose + Oxygen :D
