Question

6. Cellular respiration depends on a series of REDOX reactions. In today's lab, and in class, we learned that we can think of oxidation and reduction in terms of electronegativity and electron density. During oxidation, the oxidized species loses electron density. During reduction, the reduced species gains electron density. a. Knowing that, label the following with oxidizing agent reducing agent, oxidized product, and reduced product. They are not balanced equations (1 point each blank; 8 points total). -C-H + O= 0 O=C=0 + H O-I H C + NADH → NAD +

Answer 1

And:  

Ethane is reducing agent.

- because it get oxidized themselves and reduce another species.

O_{​​​​​​2} (Oxygen) is oxidezing agent.

- because it get reduced themselves and oxidized other species.

CO_{​​​​​2} is oxidized product.

- oxidation state of carbon in CO_{​​​​​2} increases for -3 to +4.

H_{​​​​​​2} ​​​​​​O is reduced product.

-​​​​​​ Because oxidation state of O_{​​​​​​2} decreases from 0 to -2.

Note:

. Gain of electron is Reduction.

. Loss of electron is oxidation.
