How does Cu_(2)O act as both oxidant and reductant? Explain with proper reactions showing the change of oxidation numbers in each example

Define Oxidation in terms of Oxygen and Hydrogen

Which of the following statements is correct regarding redox reactions ? (A)An increase in oxidation number of an element is called reduction (B)A decrease in oxidation number of an element is called oxidation. (C)A reagent which lowers the oxidation number of an element in a given substance is reductant. (D)A reagent which increases the oxidation number of an element in a given substance is reductant

Assertion :- In a redox reaction, the oxidation number of the oxidant decreases while that of reductant increases. Reason :- Oxidant gains electron(s) while reductant loses electron(s).
