In the equation 2H2+1O2→→2H2O if you change the 2H2 to 3H2 molecules and balance the equation, identify which statement is correct? (1 point) Responses The equation will produce three molecules of water. The equation will produce three molecules of water. Each oxygen molecule will combine with 2 hydrogen molecules with no leftover molecules. Each oxygen molecule will combine with 2 hydrogen molecules with no leftover molecules. The result of the equation will be the same. The result of the equation will be the same. It is not possible to produce water without leftover molecules.

1 answer

To balance the modified equation where you have 3 molecules of H₂ instead of 2, the new equation would look like this:

3 H₂ + O₂ → 3 H₂O

Now, let's evaluate the provided responses:

  1. The equation will produce three molecules of water. - This statement is correct. The balanced equation shows that 3 molecules of H₂ yield 3 molecules of H₂O.

  2. Each oxygen molecule will combine with 2 hydrogen molecules with no leftover molecules. - This statement is incorrect in this context. Each O₂ molecule actually combines with 3 H₂ molecules in this case.

  3. The result of the equation will be the same. - This statement is incorrect as changing the coefficients results in a different overall reaction in terms of the number of water molecules produced.

  4. It is not possible to produce water without leftover molecules. - This statement is incorrect as shown in the balanced equation; no leftover molecules occur when 3 H₂ is paired with 1 O₂.

Therefore, the correct statement in this context is: The equation will produce three molecules of water.
