Balancing Oxidation-Reduction Equations Answers

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

Which element is reduced? H✔ NOS

Which elements undergo no oxidation or reduction? O and SN and H✔ O and HN and S

Which reactant is the reducing agent?

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

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
