For example:<\/li>\n\n\n\n<li><strong>H\u2082<\/strong> means each molecule of hydrogen gas contains two hydrogen atoms.<\/li>\n\n\n\n<li><strong>O\u2082<\/strong> means each molecule of oxygen gas contains two oxygen atoms.<\/li>\n\n\n\n<li><strong>H\u2082O<\/strong> means each molecule of water contains two hydrogen atoms and one oxygen atom.<\/li>\n<\/ul>\n\n\n\n<h3 class=\"wp-block-heading\">b. <strong>Atoms and Molecules<\/strong><\/h3>\n\n\n\n<ul class=\"wp-block-list\">\n<li><strong>Atoms<\/strong>: These are the smallest units of elements, represented by their chemical symbols in the equation. In this reaction:<\/li>\n\n\n\n<li>The atoms involved are hydrogen (H) and oxygen (O).<\/li>\n\n\n\n<li>The reaction starts with hydrogen molecules (H\u2082) and oxygen molecules (O\u2082) and ends with water molecules (H\u2082O).<\/li>\n\n\n\n<li><strong>Molecules<\/strong>: A molecule consists of two or more atoms bonded together. In this equation:<\/li>\n\n\n\n<li>( H_2 ) and ( O_2 ) are molecules of hydrogen and oxygen, respectively.<\/li>\n\n\n\n<li>( H_2O ) is a molecule of water, formed when hydrogen and oxygen atoms chemically bond during the reaction.<\/li>\n<\/ul>\n\n\n\n<h3 class=\"wp-block-heading\">c. <strong>Reactants and Products<\/strong><\/h3>\n\n\n\n<ul class=\"wp-block-list\">\n<li><strong>Reactants<\/strong>: Reactants are the substances that undergo chemical changes during a reaction. In this case:<\/li>\n\n\n\n<li>The <strong>reactants<\/strong> are ( 2H_2 ) (hydrogen gas) and ( O_2 ) (oxygen gas). These are the substances that will react to form the products.<\/li>\n\n\n\n<li><strong>Products<\/strong>: Products are the substances formed as a result of the chemical reaction.

The coefficients (2) indicate the ratio of molecules involved. The subscripts (2 in (H_2) and (H_2O)) show the number of atoms per molecule. This equation follows the law of conservation of mass, meaning the number of atoms on both sides of the equation remains balanced.<\/p>\n","protected":false},"excerpt":{"rendered":"<p>Parts of a chemical Equation- Write an equation and label the following partsa.
