Interpretation:
Write and balance the equation for the given reaction.
When copper metal reacts with nitric acid to give aqueous copper(II) nitrate, water, nitrogen monoxide as products.
Concept Introduction:
The
Oxidation is the process in which either loss of electrons, oxidation number increases, or loss of hydrogen atoms takes place. An element is oxidized, when oxidation number increases.
Reduction is the process in which either gain of electrons, oxidation number decreases, or gain hydrogen atoms takes place. An element is reduced, when oxidation number decreases.
The balanced chemical equation is the equation in which number of different atoms of elements in the reactants side is similar to the product side.
