To determine the correct chemical formula, we need to use the principles of charge balance between the ions of iron (Fe) and nitrogen (N).<\/p>\n\n\n\n<ol class=\"wp-block-list\">\n<li><strong>Iron(III) ion (Fe\u00b3\u207a):<\/strong> The &#8220;III&#8221; in iron(III) indicates that iron is in the +3 oxidation state. Therefore, each iron ion has a charge of +3.<\/li>\n\n\n\n<li><strong>Nitride ion (N\u00b3\u207b):<\/strong> Nitrogen typically forms a nitride ion with a charge of -3. This is because nitrogen needs three additional electrons to complete its valence shell, giving it a -3 charge.<\/li>\n<\/ol>\n\n\n\n<p class=\"wp-block-paragraph\">Now, to form a neutral compound, the total positive charge must balance the total negative charge. This means that the number of iron ions and nitrogen ions must combine in such a way that their charges cancel out.<\/p>\n\n\n\n<p class=\"wp-block-paragraph\">Let\u2019s analyze the possible combinations:<\/p>\n\n\n\n<ul class=\"wp-block-list\">\n<li>In <strong>Fe\u2083N\u2082<\/strong>, we have 3 iron (Fe\u00b3\u207a) ions, each with a +3 charge, for a total of +9.<\/li>\n\n\n\n<li>We have 2 nitrogen (N\u00b3\u207b) ions, each with a -3 charge, for a total of -6.<\/li>\n<\/ul>\n\n\n\n<p class=\"wp-block-paragraph\">This gives us a total charge of +9 (from iron) and -6 (from nitrogen). In order to balance this, the compound needs to have a ratio of 3 iron ions to 2 nitrogen ions, ensuring that the charges cancel out in the simplest form (3 \u00d7 +3 = 9 and 2 \u00d7 -3 = -6).<\/p>\n\n\n\n<p class=\"wp-block-paragraph\">Therefore, the correct formula for iron(III) nitride is <strong>Fe\u2083N\u2082<\/strong>.<\/p>\n\n\n\n<p class=\"wp-block-paragraph\">The other options are incorrect because:<\/p>\n\n\n\n<ul class=\"wp-block-list\">\n<li><strong>Fe\u2083N<\/strong> would imply a mismatch in the charges, with 3 irons and only 1 nitrogen, which wouldn&#8217;t balance the charges.<\/li>\n\n\n\n<li><strong>FeN\u2083<\/strong> would imply 1 iron for every 3 nitrogens, which does not match the iron(III) oxidation state.<\/li>\n\n\n\n<li><strong>FeN<\/strong> or <strong>Fe\u2082N\u2083<\/strong> also result in charge imbalances for the iron(III) and nitride ions.<\/li>\n<\/ul>\n","protected":false},"excerpt":{"rendered":"<p>What is the correct formula for the compound iron(III) nitride? a) Fe3Nb) FeN3c) FeNd) Fe2N3e) Fe3N2 The correct answer and explanation is : The correct formula for the compound iron(III) nitride is e) Fe\u2083N\u2082.
