In this case, &#8220;Chromium (II)&#8221; indicates that chromium has a +2 oxidation state.<\/li>\n\n\n\n<li>Nitrate (NO\u2083) is a polyatomic ion with a -1 charge. Therefore, to balance the charge of the +2 from chromium, we need two nitrate ions.<\/li>\n<\/ul>\n\n\n\n<ol class=\"wp-block-list\">\n<li><strong>Writing the Formula<\/strong>:<\/li>\n<\/ol>\n\n\n\n<ul class=\"wp-block-list\">\n<li>Since we need two nitrate ions to balance the +2 charge from the chromium, we write the formula as Cr(NO\u2083)\u2082. Here, the parentheses are essential because they indicate that the entire NO\u2083 ion is being multiplied by 2.<\/li>\n<\/ul>\n\n\n\n<ol class=\"wp-block-list\">\n<li><strong>Analyzing the Other Options<\/strong>:<\/li>\n<\/ol>\n\n\n\n<ul class=\"wp-block-list\">\n<li><strong>a. (Cr)\u2082NO\u2083<\/strong>: This suggests two chromium atoms and one nitrate ion, which does not balance the charges correctly.<\/li>\n\n\n\n<li><strong>b. Cr2NO\u2083<\/strong>: This implies two chromium atoms with one nitrate ion, which again does not match the charge balance needed for Chromium (II).<\/li>\n\n\n\n<li><strong>c. CrNO\u2082<\/strong>: This formula suggests a different oxidation state of chromium (possibly +1) and the use of nitrite (NO\u2082) instead of nitrate, which is incorrect for this compound.<\/li>\n<\/ul>\n\n\n\n<h3 class=\"wp-block-heading\">Conclusion:<\/h3>\n\n\n\n<p>Thus, the correct chemical formula for Chromium (II) Nitrate is Cr(NO\u2083)\u2082. This indicates one chromium ion in the +2 oxidation state combined with two nitrate ions, resulting in a neutral compound. Understanding the charge balance and the use of polyatomic ions is crucial in writing the correct chemical formulas for ionic compounds.<\/p>\n","protected":false},"excerpt":{"rendered":"<p>Which is the correct formula for the compound Chromium (II) Nitrate?a.
