Question

Idenify each statement below as either oxidation or reduction.



1.

Occurs when atoms gain electrons during bonding.:

2.

Occurs when the oxidation number of an element decreases in chemical reaction.:

3.

Occurs when atoms lose electrons during bonding.

4.

F + e- ----> F-


5.

Occurs when the oxidation number of an element increases in chemical reaction.:



Occurs when the oxidation number of an element increases in chemical reaction.

6.

2I- ----> I2 + 2e-

Answer 1

Answer:

Explanation:

An oxidation reaction has the following properties;

• addition of oxygen
• removal of hydrogen
• loss of electrons
• increase in oxidation number
• increase in the number of electronegative atom surrounding an element in changing from reactants to products.

The reduction reaction is the opposite of the points mentioned above;

1. Occurs when atoms gain electrons during bonding: Reduction

2.  Occurs when the oxidation number of an element decreases in chemical reaction: Reduction

3.  Occurs when atoms lose electrons during bonding: Oxidation

4.  F + e- ----> F-  : Reduction

5.  Occurs when the oxidation number of an element increases in chemical reaction: Oxidation

6.  2I- ----> I2 + 2e- : Oxidation
