Question

Would the reaction between dihydrogen and sodium hydroxide to give sodium and water be considered a chemical change?

Answer 1

You want to do the following reaction?

`NaOH + 1/2H_2 rarr Na + H_2O`

Explanation:

This would certainly be a chemical change. It is not one that you could necessarily do, but certainly the thermodynamic parameters could be measured for the reverse reaction.
