To balance the new equation with 3H2 instead of 2H2, we have:
3H2 + O2 → ? H2O
When we balance this equation, we find:
3H2 + 1.5O2 → 3H2O
To avoid using fractional coefficients, we can multiply the entire equation by 2:
6H2 + 3O2 → 6H2O
Now, let's evaluate each statement:
-
The result of the equation will be the same. - This is incorrect because the amount of water produced is different.
-
The equation will produce three molecules of water. - This is incorrect; it actually produces six molecules of water.
-
It is not possible to produce water without leftover molecules. - This is incorrect; the new balanced equation shows that all molecules can combine perfectly with no leftover molecules.
-
Each oxygen molecule will combine with 2 hydrogen molecules with no leftover molecules. - This is incorrect; in the balanced equation, 1 molecule of O2 combines with 6 molecules of H2, not just 2.
Considering the evaluations, none of the statements given are correct for the new balanced equation. However, based on the original indication of the problem and changes made, if there's an option or rephrasing, let me know!
