Question

carbon, hydrogen, and oxygen atoms make up glucose and oxygen gas, which are the reactants of cellular respiration. carbon, hydrogen, and oxygen atoms also make up carbon dioxide gas and water, which are the products of cellular respiration. for every molecule of glucose ((c_6h_{12}o_6)) that goes into cellular respiration, the process requires 6 molecules of oxygen gas ((o_2)). complete the table.

Explanation:

Step1: Determine atoms in glucose molecule

The formula of glucose is \(C_6H_{12}O_6\). So, for 1 molecule of glucose, the number of \(O\) atoms is \(6\), and the number of \(H\) atoms is \(12\).

Step2: Calculate total atoms in reactants

• Oxygen atoms: There are \(6\) \(O\) atoms in 1 glucose molecule and \(6\times2 = 12\) \(O\) atoms in \(6\) \(O_2\) molecules. Total \(O\) atoms \(=6 + 12=18\). But in the table, since for oxygen in reactants (glucose \(O\) + oxygen gas \(O\)): glucose has \(6\) \(O\) and oxygen gas (\(6\) molecules of \(O_2\)) has \(6\times2=12\) \(O\).
• Carbon atoms: All carbon comes from glucose. Since 1 glucose molecule has \(6\) \(C\) atoms, total \(C\) atoms in reactants is \(6\).
• Hydrogen atoms: All hydrogen comes from glucose. Since 1 glucose molecule has \(12\) \(H\) atoms, total \(H\) atoms in reactants is \(12\).

Answer:

• For the oxygen atom in 1 molecule of glucose: \(6\)
• For the hydrogen atom in 1 molecule of glucose: \(12\)
• For the total number of atoms in reactants (oxygen atom): \(12\), (carbon atom): \(6\), (hydrogen atom): \(12\)
