Answer:

Physical

Explanation:

Answer 2

Dissolution of copper in concetrated trioxonitrate(v) acid is a chemical change.

Explanation:

• In chemistry, the changes occurring are classified as physical changes and chemical changes.
• The type of changes in which the compounds involved in the reaction changes its state and doesn't produces new product, it is called as physical change.
• The type of changes in which the compounds involved in the reaction changes its state and produces new product, it is called as chemical change.
• As far the given scenario, when we dissolve copper in concentrated trioxonitrate(v) acid, it gives a new products called cupric nitrate along with release of nitrogen dioxide gas and water.
• Thus, the given reaction is an example for chemical change.
