\n\n\n\nExplanation<\/h3>\n\n\n\n
Equation 1:<\/h4>\n\n\n\n
On the left, there are two ammonium (NH\u2084\u207a) ions from (NH\u2084)\u2082CO\u2083. To balance the ammonium ions on the right side, you need two NH\u2084Cl molecules. Calcium, carbonate, and chloride ions are already balanced.<\/p>\n\n\n\nEquation 2:<\/h4>\n\n\n\n
The compound Fe\u2082(SO\u2084)\u2083 contains two iron (Fe) atoms and three sulfate (SO\u2084\u00b2\u207b) groups. Each Fe(OH)\u2083 provides one iron and three hydroxide (OH\u207b) ions. Therefore, two Fe(OH)\u2083 molecules are needed for two Fe atoms. Three H\u2082SO\u2084 molecules supply the three sulfate ions. The hydroxide and hydrogen from sulfuric acid combine to form water. Since there are six OH\u207b ions total (from 2 Fe(OH)\u2083), six H\u207a ions are required to produce six water molecules.<\/p>\n\n\n\nEquation 3:<\/h4>\n\n\n\n
Al\u2082(SO\u2084)\u2083 has two aluminum atoms, so you need two Al atoms on the left. It also contains three sulfate ions, which come from three H\u2082SO\u2084 molecules. Each molecule of sulfuric acid also releases two hydrogen atoms, so three H\u2082SO\u2084 molecules yield six hydrogen atoms, which combine to form three H\u2082 molecules.<\/p>\n\n\n\n![\"\"](\"https:\/\/gaviki.com\/blog\/wp-content\/uploads\/2025\/06\/learnexams-banner10-32.jpeg\")
