Hydrogen gas is not evolved when a metal reacts with nitric acid. Why?
It is because HNO3 is a strong oxidising agent. It oxidises the H2 produced to water and itself gets reduced to any of the nitrogen oxides (N2O, NO, NO2). But magnesium (Mg) and manganese (Mn) react with very dilute HNO3 to evolve H2 gas.
Why does Magnesium float on the surface of hot water?
Magnesium reacts with hot water to form magnesium hydroxide and hydrogen. It starts floating due to the bubbles of hydrogen gas sticking to its surface.
Why do ionic compounds have high melting and boiling points?
This is because a considerable amount of energy is required to break the strong inter-ionic attraction.
Why are the sulphides and carbonates converted into their oxides during the extraction of metal?
It is easier to obtain a metal from its oxide, as compared to its sulphides and carbonates. Therefore, prior to reduction, the metal sulphides and carbonates must be converted into metal oxides.
