Redox Reaction

Oxidation is the loss of electron, meaning, there is an increase of oxidation number

• True

• False

Reduction is gaining of electron, meaning there is an increase in oxidation number.

• True

• False

______ allows organisms to liberate the energy stored in the chemical bonds of glucose.

• redox reaction

• Cellular respiration

The third step in balancing the redox reaction using oxidation-number-change is

• 5. Check the balancing for both atoms and charge.

• 4. Use coefficients to make the total increase in oxidation number equal to the total decrease in oxidation number.

• Assign oxidation numbers to each of the atoms in the equation and write the numbers above the atom.

• Use a line to connect the atoms that are undergoing a change in oxidation number.

The last step in balancing the redox reaction using oxidation-number change method is check the balancing for both atoms and charge.

• True

• False
