Which equation is balanced?
A. H2 + O2 → H2O
B. 4H2 + O2 → H2O + O
C. H2 + O2 → H2O + O2
D. 2H2 + O2 → 2H20
Yes, that's correct! D. 2H2 + O2 → 2H2O is balanced.
D. 2H2 + O2 → 2H20
Edit mistype: D. 2H2 + O2 → 2H2O
I don't usually trust AI to answer questions, but I'm pretty sure this was actually correct. Thanks :)

To determine which equation is balanced, we need to examine the number of atoms on both sides of the equation. A balanced equation has the same number and type of atoms on both sides.
Let's analyze each option:
A. H2 + O2 → H2O
On the left side, we have 2 hydrogen atoms and 2 oxygen atoms. On the right side, we have 2 hydrogen atoms and 1 oxygen atom. The number of oxygen atoms is not balanced in this equation.
B. 4H2 + O2 → H2O + O
On the left side, we have 8 hydrogen atoms and 2 oxygen atoms. On the right side, we have 2 hydrogen atoms and 3 oxygen atoms. The number of hydrogen and oxygen atoms is not balanced in this equation.
C. H2 + O2 → H2O + O2
On the left side, we have 2 hydrogen atoms and 2 oxygen atoms. On the right side, we have 2 hydrogen atoms and 3 oxygen atoms. The number of oxygen atoms is not balanced in this equation.
D. 2H2 + O2 → 2H2O
On the left side, we have 4 hydrogen atoms and 2 oxygen atoms. On the right side, we have 4 hydrogen atoms and 4 oxygen atoms. The number of hydrogen and oxygen atoms is balanced in this equation.
Therefore, the equation that is balanced is option D. 2H2 + O2 → 2H2O.
