1 answer:

5 0

Carbon dioxide and Oxygen are the two gases of air which dissolves in water by diffusion The oxygen is dissolved in water so that fishes can take in oxygen through water to breathe, this is the biological importance of this process in nature. ... Fizzy drinks contain carbon dioxide dissolved in water.

Describe how oxidation and reduction involve electrons, change oxidation numbers, and combine in oxidation reduction reactions

borishaifa [10]

Answer: Oxidation is defined as the reaction in which there is loss of electrons. It is accompanied by increase in oxidation number.

$Zn\rightarrow Zn^{2+}+2e^{-}$

Zinc in solid state has oxidation number of zero and on losing electrons changes to $Zn^{2+}$ with oxidation number of +2.

Reduction is defined as the reaction in which there is gain of electrons. It is accompanied by decrease in oxidation number.

$2H^++e^{-}\rightarrow H_2$

Hydrogen ions with +1 oxidation state gains electrons and converts to molecular hydrogen with oxidation state of zero.

In the given redox reaction, both oxidation and reduction takes place. They go hand in hand.

$Zn+H_2SO_4\rightarrow ZnSO_4 +H_2$

Zinc converts to $Zn^{2+}$ and gets oxidized. $H^+$ gains electron and convert to $H_2$ .
