Alkali metals are famous for their vigorous reactions with water, and these reactions become increasingly violent as one moves down the group. The Reaction of Alklali metals as folow: Alkali metal + water → Alkali metal hydroxide + hydrogen gas
Water is not a reaction at all. If you mean to ask if a state change in water is chemical or physical, it is physical.
An explosive reaction.
The absorption of water is not a chemical reaction.
In this reaction, most of the water is produced in the liquid phase.
The reaction between potassium oxide and water is a chemical reaction where the potassium oxide reacts with water to form potassium hydroxide. This reaction is an example of a base-metal oxide reaction.
The products of a neutralization reaction are a salt and water.
combination reaction
When a compound is broken down by the reaction with water, this is termed hydrolysis.
When water is removed, dehydration is a type of reaction that occurs.
A reaction with water (hot or cold) is a chemical reaction.
Because a water molecule is a product of the reaction
yes it is a endothermic reaction
