Let's analyze the equation you provided:
The original unbalanced equation, corrected to show the intended format, is: \[ 2H_2 + O_2 \rightarrow 2H_2O \]
Now, let's evaluate the statements given:
-
"It is not possible to produce water without leftover molecules."
- This statement is false. The balanced equation shows that 2 molecules of hydrogen (H₂) combine with 1 molecule of oxygen (O₂) to produce 2 molecules of water (H₂O) without any leftover molecules.
-
"The result of the equation will be the same."
- This statement is ambiguous, but if we are referring to the output of the balanced reaction, it is true in a way the result is consistent with the reactants.
-
"The equation will produce three molecules of water."
- This statement is false. The balanced equation produces 2 molecules of water, not 3.
-
"Each oxygen molecule will combine with 2 hydrogen molecules with no leftover molecules."
- This statement is true. According to the balanced equation, each molecule of O₂ reacts with 2 molecules of H₂ to produce 2 molecules of H₂O, with no leftover reactants.
Considering these evaluations, the correct statement is:
"Each oxygen molecule will combine with 2 hydrogen molecules with no leftover molecules."
