In the equation

Question

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

Answer 1

In the balanced equation \( 2H_2 + 1O_2 \rightarrow 2H_2O \):

• This equation shows that 2 molecules of hydrogen gas (H₂) react with 1 molecule of oxygen gas (O₂) to produce 2 molecules of water (H₂O).
• There are no leftover molecules in this reaction, as all the reactants are completely converted into the product.

Now, let's evaluate the provided statements:

1. It is not possible to produce water without leftover molecules. - This is incorrect; in this reaction, there are no leftover molecules when balanced correctly.

2. The equation will produce three molecules of water. - This is incorrect; the balanced equation produces 2 molecules of water.

3. The result of the equation will be the same. - This statement is vague and doesn't provide enough context to determine its correctness.

4. Each oxygen molecule will combine with 2 hydrogen molecules with no leftover molecules. - This statement is correct; in the given equation, 1 molecule of oxygen reacts with 2 molecules of hydrogen, and there are no leftover molecules.

Therefore, the correct statement is:

Each oxygen molecule will combine with 2 hydrogen molecules with no leftover molecules.
