What is a good reducing agent? A. A substance that is good at oxidizing another atom

B. A substance that is good at reducing another atom

C. A substance that is a good electron acceptor

D. A substance that is easily reduced in a reaction

B. A substance that is good at reducing another atom

Explanation:

Reducing agents:

Reducing agents reduced the other element are it self gets oxidized.  They have very low ionization energy and easily lose the electron.

Consider the following reactions.

4KI + 2CuCl₂  →   2CuI  + I₂  + 4KCl

the oxidation state of copper is changed from +2 to +1 so copper get reduced.  It means it gain one more electron.

CO + H₂O   →  CO₂ + H₂

the oxidation state of carbon is +2 on reactant  side and on product side it becomes  +4 so carbon get oxidized.  Carbon loses it two more electron and act as reducing agent.

Oxidizing agents:

Oxidizing agents oxidize the other elements and itself gets reduced.

Oxidation:

Oxidation involve the removal of electrons and oxidation state of atom of an element is increased.

Reduction:

Reduction involve the gain of electron and oxidation number is decreased.

petroleum? coal maybe?

answer: cellular respiration takes in food and uses it to create atp, a chemical which the cell uses for energy. usually, this process uses oxygen, and is called aerobic respiration. it has four stages known as glycolysis, link reaction, the krebs cycle, and the electron transport chain.
