Question

give two examples of oxidation and reduction​

Answer 1

Question:

give two examples of oxidation and reduction...

Example:

• The reaction between magnesium metal and oxygen to form magnesium oxide involves the oxidation of magnesium.

• The reaction between magnesium oxide and carbon at 2000C to form magnesium metal and carbon monoxide is an example of the reduction of magnesium oxide to magnesium metal.

Explanation:

Oxidation reaction: The reaction in which oxygen is gained or hydrogen is lost, is called oxidation reaction. e.g. 2Cu+O2heat 2CuO.

Reduction reaction. The reaction in which hydrogen is gained or oxygen is lost, is called reduction reaction. e.g., CuO+H2heat Cu+H2O.

Answer 2

Answer:

Example of oxidation:

1st - where an element combines with oxygen is the reaction between magnesium metal and oxygen to form magnesium oxide.

2nd - Electrochemical reactions

Example of reduction:

1st - The copper ion undergoes reduction by gaining electrons to form copper.

2nd - The magnesium undergoes oxidation by losing electrons to form the 2+ cation
