This law states that matter cannot be created or destroyed in a chemical reaction. That means the total number of atoms of each element must be the same before and after the reaction.<\/p>\n\n\n\n<p>By balancing equations, we ensure the quantities of reactants and products are correct. Even though this equation seems simple, balancing more complex reactions often involves using coefficients to equalize atom counts.<\/p>\n\n\n\n<p>In this case, the formula is already balanced naturally, so the coefficient for <strong>CO\u2082<\/strong> remains <strong>1<\/strong>.<\/p>\n\n\n\n<figure class=\"wp-block-image size-full\"><img loading=\"lazy\" decoding=\"async\" width=\"852\" height=\"1024\" src=\"https:\/\/gaviki.com\/blog\/wp-content\/uploads\/2025\/06\/learnexams-banner8-117.jpeg\" alt=\"\" class=\"wp-image-26723\" srcset=\"https:\/\/gaviki.com\/blog\/wp-content\/uploads\/2025\/06\/learnexams-banner8-117.jpeg 852w, https:\/\/gaviki.com\/blog\/wp-content\/uploads\/2025\/06\/learnexams-banner8-117-250x300.jpeg 250w, https:\/\/gaviki.com\/blog\/wp-content\/uploads\/2025\/06\/learnexams-banner8-117-768x923.jpeg 768w\" sizes=\"auto, (max-width: 852px) 100vw, 852px\" \/><\/figure>\n","protected":false},"excerpt":{"rendered":"<p>When the equation CaCO3 \u2192 CaO + CO2 is balanced, the coefficient of carbon dioxide is 1. 2. 3. 4.
