Please koi 4250 thanks Karva do please​

Answer 1

Explanation:

When dilute HCl is added to a small amount of copper oxide in a beaker, a bluish green solution is formed. Since, the metal oxides such as Copper oxide (CuO) is basic in nature, it reacts with acids such as HCl to form the corresponding salt and water. The reaction that occurs is called neutralization reaction

Answer 2

When dilute HCl is added to a small amount of copper oxide in a beaker, a greenish-yellow gas is released and a bluish-green solution is formed. Since the metal oxides such as a Copper oxide (CuO) are basic in nature, it reacts with acids such as HCl to form the corresponding salt and water.
