Unraveling it from a Chemical Perspective<\/h3>\n<p data-sourcepos=\"15:1-15:51\">The thermite reaction utilizes aluminum&#8217;s strong reducing power. The chemical equation is as follows:<\/p>\n<p data-sourcepos=\"17:1-17:94\">\n<p>ceFe2O3+2Al\u00a0\u2212&gt;2Fe\u00a0+Al2O3<\/p>\n<p data-sourcepos=\"19:1-19:233\">As this equation shows, iron(III) oxide (<span class=\"math-inline\">Fe2O3<\/span>) and aluminum (<span class=\"math-inline\">Al<\/span>) react to produce iron (<span class=\"math-inline\">Fe<\/span>) and aluminum oxide (<span class=\"math-inline\">Al2O3<\/span>).<\/p>\n<p data-sourcepos=\"21:1-22:139\">Let&#8217;s take a closer look. <strong>Aluminum<\/strong> is a highly reactive metal with a strong affinity for oxygen. <strong>Iron(III) oxide<\/strong>, on the other hand, is a compound of iron and oxygen. In this experiment, the aluminum &#8220;steals&#8221; the oxygen from the iron(III) oxide, causing the iron to separate as a pure element, while the aluminum itself changes into aluminum oxide.<\/p>\n<p data-sourcepos=\"24:1-24:116\">This is an <strong>exothermic reaction<\/strong> that generates a large amount of heat, and a key feature is that the iron produced melts into a molten lump. The temperature is said to reach over 2000\u00b0C. This high temperature is utilized in applications like welding railway tracks.<\/p>\n<h3 data-sourcepos=\"26:1-26:19\">Practiced in the Science Club!
