Final answer:
The total number of atoms in the products when one molecule of glucose reacts completely with three molecules of oxygen is 108 atoms.
Step-by-step explanation:
The balanced chemical equation for the reaction between one molecule of glucose (C6H12O6) and three molecules of oxygen (O2) is:
C6H12O6 + 6O2 -> 6CO2 + 6H2O
From the balanced equation, we can see that 6 molecules of carbon dioxide (CO2) and 6 molecules of water (H2O) are formed as products.
To determine the total number of atoms in the products, we need to calculate the number of atoms in each molecule of CO2 and H2O. The formula for carbon dioxide is CO2, which contains 1 carbon atom and 2 oxygen atoms. The formula for water is H2O, which contains 2 hydrogen atoms and 1 oxygen atom.
Therefore, the total number of atoms in the products is: 6 molecules x (1 carbon atom + 2 oxygen atoms) + 6 molecules x (2 hydrogen atoms + 1 oxygen atom) = 24 carbon atoms + 72 oxygen atoms + 12 hydrogen atoms = 108 atoms in total.
