Here, (4 \\text{Ca(OH)}_2) means there are four molecules (or moles, in the context of larger quantities) of calcium hydroxide. Each molecule of (\\text{Ca(OH)}_2) consists of one calcium (Ca) atom, two oxygen (O) atoms, and two hydrogen (H) atoms.<\/li>\n\n\n\n<li><strong>Expanding the Formula<\/strong>: If we consider (4 \\text{Ca(OH)}_2) at the atomic level, the coefficient &#8220;4&#8221; applies to the entire (\\text{Ca(OH)}_2) unit. Therefore:<\/li>\n<\/ol>\n\n\n\n<ul class=\"wp-block-list\">\n<li><strong>Calcium atoms<\/strong>: (4 \\times 1 = 4) Ca atoms<\/li>\n\n\n\n<li><strong>Oxygen atoms<\/strong>: (4 \\times 2 = 8) O atoms<\/li>\n\n\n\n<li><strong>Hydrogen atoms<\/strong>: (4 \\times 2 = 8) H atoms<\/li>\n<\/ul>\n\n\n\n<ol class=\"wp-block-list\">\n<li><strong>Usage in Chemical Equations<\/strong>: Coefficients are critical in balancing chemical reactions. They help maintain the law of conservation of mass, ensuring the same number of each atom on both sides of a reaction. By adjusting coefficients, chemists can balance the equation, making sure it correctly represents what happens in the reaction.<\/li>\n<\/ol>\n\n\n\n<p>In summary, the coefficient in (4 \\text{Ca(OH)}_2) is 4, and it indicates the presence of four separate (\\text{Ca(OH)}_2) molecules or moles, impacting the total number of each atom present in a reaction or compound.<\/p>\n","protected":false},"excerpt":{"rendered":"<p>What&#8217;s the coefficient in 4Ca(OH)2 ? \u200b The Correct Answer and Explanation is : In the formula (4 \\text{Ca(OH)}_2), the coefficient is 4.
