This law states that matter cannot be created or destroyed in a chemical reaction. Therefore, the number of atoms of each element must be the same on both the reactant and product sides of the equation.<\/p>\n\n\n\n<p>Let us consider the reaction between sodium (Na) and water (H\u2082O). The unbalanced chemical equation is: Na+H2O\u2192NaOH+H2Na + H_2O \\rightarrow NaOH + H_2Na+H2\u200bO\u2192NaOH+H2\u200b<\/p>\n\n\n\n<p>Step 1: <strong>Balance the sodium (Na) atoms.<\/strong><br>There is 1 Na atom on the left and 1 Na atom in NaOH on the right. So far, sodium is balanced.<\/p>\n\n\n\n<p>Step 2: <strong>Balance the oxygen (O) atoms.<\/strong><br>There is 1 oxygen atom in H\u2082O on the left and 1 oxygen atom in NaOH on the right. Oxygen is also balanced.<\/p>\n\n\n\n<p>Step 3: <strong>Balance the hydrogen (H) atoms.<\/strong><br>On the left side, there are 2 hydrogen atoms in H\u2082O. On the right side, NaOH contains 1 hydrogen atom and H\u2082 is a molecule made of 2 hydrogen atoms.<\/p>\n\n\n\n<p>Adding up the hydrogen atoms on the right:<\/p>\n\n\n\n<ul class=\"wp-block-list\">\n<li>1 H from NaOH<\/li>\n\n\n\n<li>2 H from H\u2082 molecule (Note: H\u2082 means two hydrogen atoms bonded together)<\/li>\n<\/ul>\n\n\n\n<p>This results in 3 hydrogen atoms on the product side but only 2 on the reactant side. This suggests the equation is unbalanced.<\/p>\n\n\n\n<p>To fix this, multiply H\u2082O and NaOH by 2: 2Na+2H2O\u21922NaOH+H22Na + 2H_2O \\rightarrow 2NaOH + H_22Na+2H2\u200bO\u21922NaOH+H2\u200b<\/p>\n\n\n\n<p>Now check again:<\/p>\n\n\n\n<ul class=\"wp-block-list\">\n<li>Sodium: 2 atoms on both sides.<\/li>\n\n\n\n<li>Oxygen: 2 atoms from 2 H\u2082O on the left and 2 in 2 NaOH on the right.<\/li>\n\n\n\n<li>Hydrogen: 4 atoms from 2 H\u2082O on the left, and 2 in 2 NaOH + 2 in H\u2082 on the right.<\/li>\n<\/ul>\n\n\n\n<p>All elements are now balanced, and the equation is correct.<\/p>\n\n\n\n<figure class=\"wp-block-image size-full\"><img decoding=\"async\" src=\"https:\/\/learnexams.com\/blog\/wp-content\/uploads\/2025\/06\/learnexams-banner8-276.jpeg\" alt=\"\" class=\"wp-image-233585\"\/><\/figure>\n","protected":false},"excerpt":{"rendered":"<p>Na +H2O &#8212; NaOH +H2 .
