Correct Answer:<\/strong> Explanation:<\/strong> Fe\u2082O\u2083 is a neutral compound made up of two iron (Fe) atoms and three oxygen (O) atoms. Oxygen, in most compounds, has a standard oxidation number of -2. Since there are three oxygen atoms, the total oxidation from oxygen is:<\/p>\n\n\n\n 3 \u00d7 (-2) = -6<\/p>\n\n\n\n Now, let the oxidation number of each iron atom be x<\/strong>. There are two iron atoms, so the total contribution from iron is:<\/p>\n\n\n\n 2 \u00d7 x = 2x<\/p>\n\n\n\n According to the rule mentioned earlier, the sum of all oxidation numbers must equal zero. So we set up the equation:<\/p>\n\n\n\n 2x + (-6) = 0 Therefore, the oxidation number of each iron atom in Fe\u2082O\u2083 is +3<\/strong>.<\/p>\n\n\n\n This means that in Fe\u2082O\u2083, iron has lost three electrons per atom to reach this oxidation state. In chemical terms, Fe is acting as a cation (positively charged ion), and oxygen is acting as an anion (negatively charged ion). Specifically, Fe\u00b3\u207a ions combine with O\u00b2\u207b ions in a ratio that balances the total charges to zero.<\/p>\n\n\n\n Fe\u2082O\u2083 is also known as iron(III) oxide. The Roman numeral III in the name confirms that iron is in the +3 oxidation state in this compound. This is important in redox chemistry and reactions such as smelting, where changes in oxidation number reflect the transfer of electrons.<\/p>\n\n\n\n The oxidation number of Fe in Fe2O3 is The Correct Answer and Explanation is: Correct Answer:The oxidation number of Fe in Fe\u2082O\u2083 is +3. Explanation:To find the oxidation number of iron (Fe) in the compound Fe\u2082O\u2083, we need to consider the oxidation rules for compounds. One key rule is that the sum of the oxidation […]<\/p>\n","protected":false},"author":1,"featured_media":0,"comment_status":"open","ping_status":"open","sticky":false,"template":"","format":"standard","meta":{"footnotes":""},"categories":[1],"tags":[],"class_list":["post-27778","post","type-post","status-publish","format-standard","hentry","category-quiz-questions"],"_links":{"self":[{"href":"https:\/\/gaviki.com\/blog\/wp-json\/wp\/v2\/posts\/27778","targetHints":{"allow":["GET"]}}],"collection":[{"href":"https:\/\/gaviki.com\/blog\/wp-json\/wp\/v2\/posts"}],"about":[{"href":"https:\/\/gaviki.com\/blog\/wp-json\/wp\/v2\/types\/post"}],"author":[{"embeddable":true,"href":"https:\/\/gaviki.com\/blog\/wp-json\/wp\/v2\/users\/1"}],"replies":[{"embeddable":true,"href":"https:\/\/gaviki.com\/blog\/wp-json\/wp\/v2\/comments?post=27778"}],"version-history":[{"count":1,"href":"https:\/\/gaviki.com\/blog\/wp-json\/wp\/v2\/posts\/27778\/revisions"}],"predecessor-version":[{"id":27780,"href":"https:\/\/gaviki.com\/blog\/wp-json\/wp\/v2\/posts\/27778\/revisions\/27780"}],"wp:attachment":[{"href":"https:\/\/gaviki.com\/blog\/wp-json\/wp\/v2\/media?parent=27778"}],"wp:term":[{"taxonomy":"category","embeddable":true,"href":"https:\/\/gaviki.com\/blog\/wp-json\/wp\/v2\/categories?post=27778"},{"taxonomy":"post_tag","embeddable":true,"href":"https:\/\/gaviki.com\/blog\/wp-json\/wp\/v2\/tags?post=27778"}],"curies":[{"name":"wp","href":"https:\/\/api.w.org\/{rel}","templated":true}]}}
The oxidation number of Fe in Fe\u2082O\u2083 is +3<\/strong>.<\/p>\n\n\n\n
To find the oxidation number of iron (Fe) in the compound Fe\u2082O\u2083, we need to consider the oxidation rules for compounds. One key rule is that the sum of the oxidation numbers of all atoms in a neutral compound must equal zero.<\/p>\n\n\n\n
