One of its important chemical properties is its ability to decompose into water (H\u2082O) and oxygen gas (O\u2082). This reaction can occur slowly at room temperature, but it is often accelerated by light, heat, or the presence of catalysts such as manganese dioxide (MnO\u2082) or catalase (an enzyme found in living tissues).<\/p>\n\n\n\n<p>To understand the reaction, let\u2019s examine the chemical components:<\/p>\n\n\n\n<ul class=\"wp-block-list\">\n<li><strong>Reactant<\/strong>: Hydrogen peroxide, H\u2082O\u2082<\/li>\n\n\n\n<li><strong>Products<\/strong>: Water, H\u2082O, and oxygen gas, O\u2082<\/li>\n<\/ul>\n\n\n\n<p>First, we write the unbalanced chemical equation: H2O2\u2192H2O+O2H_2O_2 \\rightarrow H_2O + O_2<\/p>\n\n\n\n<p>Next, we balance the equation.

On the right, H\u2082O has 1 oxygen atom, and O\u2082 has 2 oxygen atoms (but it\u2019s a diatomic molecule, so it&#8217;s trickier to balance).<\/li>\n<\/ul>\n\n\n\n<p>To balance the atoms:<\/p>\n\n\n\n<ol class=\"wp-block-list\">\n<li>Place a coefficient of <strong>2<\/strong> in front of H\u2082O\u2082 to have 4 oxygen atoms and 4 hydrogen atoms. 2H2O2\u2192H2O+O22H_2O_2 \\rightarrow H_2O + O_2<\/li>\n\n\n\n<li>Now add a <strong>2<\/strong> in front of H\u2082O to get 4 hydrogen atoms and 2 oxygen atoms. 2H2O2\u21922H2O+O22H_2O_2 \\rightarrow 2H_2O + O_2<\/li>\n<\/ol>\n\n\n\n<p>Now the equation is balanced:<\/p>\n\n\n\n<ul class=\"wp-block-list\">\n<li>Hydrogen: 4 atoms on both sides<\/li>\n\n\n\n<li>Oxygen: 4 atoms on both sides (2 from 2H\u2082O and 2 from O\u2082)<\/li>\n<\/ul>\n\n\n\n<p>This decomposition is an example of a redox reaction, where oxygen is both oxidized and reduced.
