H2) -----> H^+ + OH^-
Is this equation balanced
Yes, it is balanced, but it is not what happens in water. Here is what happens in water..
2H2O (l)>>>H30+ + OH-
BALANCED
To determine if this chemical equation is balanced, we need to make sure that the number of atoms of each element on both sides of the equation is equal. Let's analyze the equation you provided:
H2 -----> H+ + OH-
On the left side, we have 2 hydrogen atoms (H2). On the right side, we have 1 hydrogen atom in H+ and 1 oxygen atom in OH-. So, we have a total of 2 hydrogen atoms and 1 oxygen atom on the right side.
As we can see, the equation is not balanced because the number of hydrogen atoms on the left side is not equal to the number of hydrogen atoms on the right side. To balance the equation, we need to adjust the coefficients in front of the chemical species.
To balance the hydrogen atoms, we can put a coefficient of 2 in front of H+:
H2 -----> 2H+ + OH-
Now, on the right side, we have 2 hydrogen atoms from the H+ and 1 hydrogen atom from the OH-. This results in a total of 3 hydrogen atoms on the right side, which is not equal to the 2 hydrogen atoms on the left side.
To balance the equation fully, we also need to put a coefficient of 2 in front of the water (H2O) molecule:
H2 + 2H2O -----> 2H+ + 2OH-
Now, on the right side, we have 2 hydrogen atoms from the 2H+ ions and 2 hydrogen atoms from the 2OH- ions, which totals to 4 hydrogen atoms. On the left side, we have 2 hydrogen atoms from the H2 molecule and 2 hydrogen atoms from the 2H2O molecules, which totals to 4 hydrogen atoms as well.
Therefore, the balanced equation is:
H2 + 2H2O -----> 2H+ + 2OH-
