Answers
Answer:
Hey mate
Explanation:
Oxidation Reaction is the reaction I which Addition of oxygen or removal of hydrogen can be observed....
The substance that is oxidized is Na
Answer:
(a) Oxidation-reaction is a type of chemical reaction in which the oxidation states of atoms are changed. Redox reactions are characterized by the actual or formal transfer of electrons between chemical species, most often with one species undergoing oxidation while another species undergoes reduction.
(b) Reaction between magnesium metal and oxygen to form magnesium oxide involves the oxidation of magnesium.
(c) Sodium (Na) gains oxygen and gets oxidised to sodium oxide.
Explanation:
A substance is said to oxidised if it loses its electrons or addition of oxygen to the substance. The term oxidation was used to describe reactions where an element combines with oxygen. Oxidation meant gaining oxygen and Reduction meant losing oxygen.
A reaction within which there is both oxidation and reduction is called a redox reaction.
