Is reacting sodium metal with water a physical or chemical change

Explanation:

Reaction of sodium metal with water is a chemical change . Sodium reacts with water to form sodium hydroxide. This is also an example of exothermic reaction as heat is released in this process. Sodium reacts vigoursly with water , it even reacts with the moisture present in the air . So it is stored in kerosene oil .

The reaction of sodium with water is :-

.

The reaction of sodium metal with water is a chemical change, as a result formation of sodium hydroxide occurs.

A Chemical change is any change that occurs to substances which when combine to form a new substance or decompose to form new substances. Here there occurs an internal consistency of the matter involved in that particular change.A physical change is a change with involves the changes in the size, shape, texture, etc. of any substance.

The following points to be noted for the reaction of sodium with water:

The sodium reacts with water to give sodium hydroxide.The presence of the single outermost electron (3s1) in sodium makes the metal highly reactive.This is a chemical change which is an exothermic reaction, which means the reaction results in the liberation of heat during the process.Sodium is a very highly reactive metal, which can even react with moisture present in the air.To avoid any unnecessary reactions, sodium is stored in kerosene, where it seems to be inert.

Therefore, the reaction of sodium with water is a chemical change.
