Copper does not react with dilute nitric acid because it is less reactive compared to magnesium, manganese, aluminum, zinc, and iron. The lack of bubbles and unchanged temperature during the reaction with copper confirm that it does not react with ...

The rate of formation of bubbles when metals react with dilute nitric acid depends on the reactivity of the metal. More reactive metals like magnesium react faster and produce bubbles more rapidly compared to less reactive metals.

Magnesium and manganese react with very dilute nitric acid to evolve hydrogen gas because they are more reactive metals that can displace hydrogen from nitric acid, even in its oxidizing environment.

Hydrogen gas is not evolved when a metal reacts with nitric acid because nitric acid (HNO3) is a strong oxidizing agent. It oxidizes the hydrogen gas produced to water while itself getting reduced to various nitrogen oxides (N2O, NO, NO2).

Metals such as lead, copper, silver, and gold do not react with water at all under normal conditions.

Metals like aluminium, iron, and zinc do not react with cold or hot water, but they react with steam to form the metal oxide and hydrogen.

Magnesium starts floating when it reacts with hot water because the bubbles of hydrogen gas formed during the reaction stick to its surface, reducing its density and causing it to float.

Calcium starts floating because the bubbles of hydrogen gas formed during the reaction stick to the surface of the metal, reducing its density and causing it to float.

No, not all metals react with water. Metals like potassium, sodium, and calcium react with water, but others may not. The reactivity of metals with water varies depending on their position in the reactivity series. Metals like gold and silver, ...

Metal oxides soluble in water dissolve in it to form metal hydroxides.
