Balancing Oxidation-Reduction Equations

Question 1

Now identify the element oxidized and the element reduced. Which element is oxidized? HNO✔ S

Revolt · Accepted Answer

D: S

Question 2

Balance this equation step by step. To identify which element is oxidized and which element is reduced, you must assign numbers to all elements.

Revolt · Accepted Answer

C: oxidation

Question 3

Next, identify the oxidizing agent and the reducing agent by comparing the oxidation numbers of elements before and after reaction.The compound containing the element that increases oxidation number is

Revolt · Accepted Answer

A: oxidized.

Question 5

Next, determine how many electrons are involved in each half-reaction. What information will you use to make this determination?The number of electrons involved in each half-reaction is equal to the oxidation numbers for each element as a result of reaction.

Revolt · Accepted Answer

B: difference between

Question 6

Next, determine how many electrons are involved in each half-reaction.How many electrons should be assigned to which side of this half-reaction equation?

Revolt · Accepted Answer

C: 3 electrons on reactant side

Question 7

You now have these half-reaction equations: What is the next step?

Revolt · Accepted Answer

B: Multiply each equation by a factor to give the same number of electrons in both.
