To determine the name of the compound, we need to analyze the oxidation states of the elements involved.<\/p>\n\n\n\n<ol class=\"wp-block-list\">\n<li><strong>Oxidation States of Iron<\/strong>: Iron (Fe) can have multiple oxidation states, primarily +2 and +3. In this compound, the oxygen atoms are always in the -2 oxidation state (since oxygen typically forms oxide ions, O\u00b2\u207b).<\/li>\n\n\n\n<li><strong>Balancing Charges<\/strong>: The formula Fe\u2082O\u2083 tells us that there are two iron atoms and three oxygen atoms in the compound. If we assume that the oxidation state of iron is +3, the total positive charge from the iron atoms is 2 * (+3) = +6. To balance this, the three oxygen atoms each contribute a -2 charge, and the total negative charge from oxygen atoms is 3 * (-2) = -6. The charges balance out, confirming that each iron atom has an oxidation state of +3 in this compound.<\/li>\n\n\n\n<li><strong>Naming the Compound<\/strong>: When naming binary ionic compounds like this one, the name is derived from the oxidation states of the elements. The oxidation state of iron in this case is +3, so the name of the compound is &#8220;Iron (III) oxide,&#8221; where the Roman numeral &#8220;(III)&#8221; indicates the +3 oxidation state of iron, and &#8220;oxide&#8221; refers to the oxygen component of the compound.<\/li>\n<\/ol>\n\n\n\n<p>Now let\u2019s quickly go over the other options:<\/p>\n\n\n\n<ul class=\"wp-block-list\">\n<li><strong>A) Iron (II) oxide<\/strong>: This would be correct if iron had an oxidation state of +2, but in Fe\u2082O\u2083, the oxidation state of iron is +3.<\/li>\n\n\n\n<li><strong>B) Iron oxide Carbon (VI)<\/strong>: This option is incorrect, as there is no carbon in the compound.<\/li>\n\n\n\n<li><strong>D) Diiron trioxide<\/strong>: While this is a valid name in a systematic sense (using prefixes for the number of atoms), it is not the standard IUPAC name for this compound, which uses Roman numerals for the oxidation state.<\/li>\n<\/ul>\n\n\n\n<p>Thus, <strong>C) Iron (III) oxide<\/strong> is the correct and most widely accepted name for Fe\u2082O\u2083.<\/p>\n","protected":false},"excerpt":{"rendered":"<p>What is the name of this compound: Fe2O3 ?
