Melting is a physical process; reaction with sodium is a chemical process.
The melting of Sodium is a physical change.
Chemical change (which results in physical change).
Physical Change
Yea it is a chemical change. The Sodium reacts with water in a chemical reaction in which the sodium displaces the hydrogen in the water, creating sodium oxide and hydrogen gas. The heat from the reaction ignites the hydrogen, which creates the explosion.

It's physical
chemical change a physical change changes the apperance chemicals changes change the substance
That is a chemical change. You are seeing a chemical reaction, where the sodium reacts with the water, forming sodium hydroxide and hydrogen gas.
u asking me for my answer and u can not give me one
Sodium is a chemical element, not a change.
No this is a chemical change- sodium reacts with chlorine gas to form sodium chloride and a lot of heat.
It is a chemical reaction for not only has the state changed of NaOH, but the identity of the substances have also changed.NaOH + H2O --> Na+ + OH-The "H2O" is not a reactant. It's actually supposed to go over the arrow. Sorry.Nonetheless, the dissolution of NaOH will increase the Hydroxide concentration, thus making it more basic. It will not change the identity of H2O.

The dissolution of sodium chloride is considered as a physical process.
