FeSO4Fe2O3 +SO2 +SO3b) Is this reaction endothermic or exothermic? |
|
Answer» Start by IDENTIFYING the oxidation state for each of the ELEMENT:+2Fe+6S−2O4→+3Fe2−2O3++4S−2O2++6S−2O3−NOT BALANCEDOnly three of the four chemicals- FeSO4 , FE2O3 , and SO2 are directly involved in the redox reaction.The oxidation state of iron Fe has increased from+2 in +2Fe+6S−2O4 to+3 in +3Fe2−2O3 by ONEAND therefore Fe is oxidized.The oxidation state of sulfur S has declined from+6 in +2Fe+6S−2O4 to+4 in +4S−2O2 by twoand therefore some of the sulfur ATOMS have been reduced.Explanation:Make me brainliest ✨ |
