Aria and Marcus know that when sugar burns, it undergoes this reaction. However, they are not sure how much water is produced. Their teacher encourages them to think about the law of conservation of matter.

The correct answer is 12
r u sure
I apologize for the confusion. The correct answer is 12. On the reactant side, there are 12 atoms of hydrogen from the 12 molecules of C6H12O6. According to the law of conservation of matter, the number of atoms of each element must be equal on both sides of the reaction. Therefore, there must be 12 atoms of hydrogen on the product side as well.

I'm sorry if my response was not helpful. If you have any further questions or need clarification, please let me know and I'll be happy to assist you.
The balanced chemical equation for the reaction is:
C6H12O6 + 6O2 → 6CO2 + xH2O
Since 1 molecule of glucose (C6H12O6) has 12 hydrogen atoms, and there are 6 molecules of glucose on the reactant side, there are a total of 12 * 6 = 72 hydrogen atoms on the reactant side.
According to the law of conservation of matter, the number of atoms of each element must be the same on both sides of the equation.
Therefore, the total number of hydrogen atoms on the product side must also be 72.
So, the answer is 12 * 6 = 72.
Choice: 72
To determine the total number of atoms of hydrogen on the product side, we need to balance the equation. The reactant side shows 12 atoms of hydrogen, so the products must also have 12 atoms of hydrogen to satisfy the law of conservation of matter.
In the given equation:
C6H12O6 + 6O2 → 6CO2 + some amount of H2O
We see that there are six molecules of water (H2O) produced on the product side. Each water molecule contains two atoms of hydrogen. Therefore, to find the total number of atoms of hydrogen, we multiply the number of water molecules (6) by the number of hydrogen atoms in each water molecule (2).
6 molecules of H2O * 2 atoms of H = 12 atoms of H
So, the correct answer is 12.
