Both the global and internal nitrogen cycles are biologically regulated, but the transformations are the result of biotic and abiotic interactions.Electron transfersare at the center of the transformations which make the N cycle. Nitrogen loses and gains electrons during abiotic and biotic chemical tran...
解析 8(a)(i)Fractional distillation8(a)(ii)It changes from moving rapidly in random directions / moving at greaspeed in different directions to sliding over each other randomly /indifferent directions within the liquid.8(b)(i)Each oxygen atom gains two electrons from magnesium [1], formingoxi...
A metal atom forms a cation when it loses electrons while a nonmetal atom forms an anion when it gains electrons. When a metal cation and a nonmetal anion are combined by the electrostatic force of attraction, an ionic compound is produced....
Theoxidation state(or oxidation number) of an atom as a free element, or in a compound or an ion represents its hypothetical charge, assuming all bonds are ionic. The change of oxidation states of an atom through a reaction indicate if the atom has lost or gained electrons through ...

A redox reaction involves the transfer of electrons between elements in the reactants where one element is oxidized (loses electrons) and another is reduced (gains electrons). In order to balance redox reactions, we must start by b...
When nitric acid loses its proton, it forms a nitrogen oxoanion called nitrate. Answer and Explanation: Given: Compound {eq}\rm NO_3^- {/eq} Assume the oxidation state of N as y. Oxygen gains 2 electrons to complete its octet, and the oxidation state......
