NaOH<\/strong> (Sodium hydroxide).<\/p>\n\n\n\n<h3 class=\"wp-block-heading\">Explanation:<\/h3>\n\n\n\n<p>To determine which compound contains a polyatomic ion, we need to understand what a polyatomic ion is. A polyatomic ion is a charged ion composed of two or more atoms covalently bonded, acting as a single unit. These ions can be either positively charged (cations) or negatively charged (anions). Common examples include sulfate (SO\u2084\u00b2\u207b), ammonium (NH\u2084\u207a), and hydroxide (OH\u207b).<\/p>\n\n\n\n<p>Now, let\u2019s examine each compound:<\/p>\n\n\n\n<ol class=\"wp-block-list\">\n<li><strong>NH\u2083 (Ammonia)<\/strong>: This is a neutral molecule, not an ion. It does not contain a polyatomic ion. It consists of one nitrogen atom and three hydrogen atoms, all covalently bonded. Since it does not have a charge, it is not considered an ion and does not contain a polyatomic ion.<\/li>\n\n\n\n<li><strong>HCl (Hydrochloric acid)<\/strong>: This compound consists of hydrogen and chlorine. It forms a simple ionic bond between H\u207a and Cl\u207b ions when dissolved in water, but these ions are individual atoms, not polyatomic ions. So, it does not contain a polyatomic ion.<\/li>\n\n\n\n<li><strong>NaOH (Sodium hydroxide)<\/strong>: Sodium hydroxide consists of the sodium ion (Na\u207a) and the hydroxide ion (OH\u207b). The hydroxide ion (OH\u207b) is a polyatomic ion composed of oxygen and hydrogen atoms, bonded together and carrying a negative charge. Therefore, NaOH contains a polyatomic ion.<\/li>\n\n\n\n<li><strong>MgBr\u2082 (Magnesium bromide)<\/strong>: This compound contains magnesium ions (Mg\u00b2\u207a) and bromide ions (Br\u207b). Both ions are monatomic (consisting of single atoms), so this compound does not contain a polyatomic ion.<\/li>\n\n\n\n<li><strong>Ca\u2083N\u2082 (Calcium nitride)<\/strong>: This compound consists of calcium ions (Ca\u00b2\u207a) and nitride ions (N\u00b3\u207b). The nitride ion is a monatomic ion, so this compound does not contain a polyatomic ion.<\/li>\n<\/ol>\n\n\n\n<p>Thus, the only compound in the list that contains a polyatomic ion is <strong>NaOH<\/strong>.<\/p>\n","protected":false},"excerpt":{"rendered":"<p>Which of the following compounds contains a polyatomic ion?a.
