Fe\u2082S\u2083<\/strong>.<\/p>\n\n\n\n<h3 class=\"wp-block-heading\">Explanation:<\/h3>\n\n\n\n<p>Iron(III) sulfide is a compound formed between iron and sulfur. In this context, the &#8220;III&#8221; in iron(III) indicates that iron has a +3 oxidation state. Understanding the oxidation states of the elements involved is crucial for determining the correct chemical formula.<\/p>\n\n\n\n<ol class=\"wp-block-list\">\n<li><strong>Oxidation States<\/strong>:<\/li>\n<\/ol>\n\n\n\n<ul class=\"wp-block-list\">\n<li>Iron (Fe) can have multiple oxidation states, including +2 and +3. In iron(III) sulfide, iron is in the +3 oxidation state.<\/li>\n\n\n\n<li>Sulfur (S) typically has an oxidation state of -2 in sulfide compounds.<\/li>\n<\/ul>\n\n\n\n<ol class=\"wp-block-list\">\n<li><strong>Balancing Charges<\/strong>:<\/li>\n<\/ol>\n\n\n\n<ul class=\"wp-block-list\">\n<li>To determine the correct formula, we need to balance the total positive and negative charges. Each iron atom contributes a +3 charge, while each sulfur atom contributes a -2 charge.<\/li>\n\n\n\n<li>To balance the charges in the compound, we can set up the following equation:\n<ul class=\"wp-block-list\">\n<li>If we let ( x ) be the number of iron atoms and ( y ) be the number of sulfur atoms, we need to solve for ( x ) and ( y ) in the equation:<br>[<br>3x + (-2y) = 0<br>]<\/li>\n<\/ul>\n<\/li>\n\n\n\n<li>To achieve charge neutrality, we find that for every 2 iron atoms (+6) we need 3 sulfur atoms (-6):\n<ul class=\"wp-block-list\">\n<li>Thus, ( 2(3) + 3(-2) = 0 ).<\/li>\n<\/ul>\n<\/li>\n<\/ul>\n\n\n\n<ol class=\"wp-block-list\">\n<li><strong>Formula Construction<\/strong>:<\/li>\n<\/ol>\n\n\n\n<ul class=\"wp-block-list\">\n<li>This gives us the formula ( \\text{Fe}_2\\text{S}_3 ). Here, we have two iron atoms and three sulfur atoms, which balances the charges perfectly.<\/li>\n<\/ul>\n\n\n\n<ol class=\"wp-block-list\">\n<li><strong>Chemical Properties<\/strong>:<\/li>\n<\/ol>\n\n\n\n<ul class=\"wp-block-list\">\n<li>Iron(III) sulfide is a solid compound that can form through various reactions, including the direct combination of elemental iron and sulfur at elevated temperatures.<\/li>\n<\/ul>\n\n\n\n<p>In summary, the correct chemical formula for iron(III) sulfide, based on oxidation states and charge balancing, is <strong>Fe\u2082S\u2083<\/strong>. This formula reflects the stoichiometric ratio of iron to sulfur in the compound, confirming that it comprises two iron atoms for every three sulfur atoms.<\/p>\n","protected":false},"excerpt":{"rendered":"<p>What is the correct formula for iron(III) sulfide?A.
