Since we have 6 sulfur atoms on the left, we need to divide this by 8 and balance by adjusting the coefficient of S\u2088. Thus, 3 molecules of S\u2088 will give us 24 sulfur atoms.<\/li>\n<\/ul>\n<\/li>\n<\/ol>\n\n\n\n<h3 class=\"wp-block-heading\">Conclusion:<\/h3>\n\n\n\n<p>The decomposition of Al\u2082S\u2083 results in aluminum metal and sulfur in its S\u2088 form. The balanced equation ensures that the number of atoms for each element is the same on both sides of the reaction.<\/p>\n\n\n\n<figure class=\"wp-block-image size-full\"><img decoding=\"async\" src=\"https:\/\/learnexams.com\/blog\/wp-content\/uploads\/2025\/07\/learnexams-banner6-931.jpeg\" alt=\"\" class=\"wp-image-259296\"\/><\/figure>\n","protected":false},"excerpt":{"rendered":"<p>Consider the decomposition of aluminum sulfide into aluminum metal and solid S\u2088 (one of the forms of sulfur).
