Question

A Which of the following statements is (are) true? Oxidation and reduction a cannet oecur independently of each other, b accompany all chemical changes e describe the loss and gain of electron(s), respectively d result in a change in the oxidation states of the species involved. e a, e, and d are true 3. Which of the following reactions is a redox reaction? a) K,00,+BaCl, BaCO, +2KCI (b) Cu+SCu (c) Pb +2BrPbBr a. (a) only b. (b) only c. (c) only d. (a) and (c) e. (b) and (c) 4. How many moles of electrons are transferred in the following reaction? a. o b. 2 C. d. 6 e. not enough information given

Explanation / Answer

Ans 2

Option E is the correct answer

A redox reaction is always occurs with Oxidation reaction and reduction reaction simultaneously and can't occur independently.

It represents the All chemical and physical changes.

In the oxidation reaction, loss of electrons occur

In the reduction reaction, gain of electrons occur.

Oclxidation state of elements change from high to low i.e. Reduction and from low to high i.e. Oxidation.

All options are true
