1 answer

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:

  1. "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.
  2. "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.
  3. "The equation will produce three molecules of water."

    • This statement is false. The balanced equation produces 2 molecules of water, not 3.
  4. "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."
