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.
It is not possible to produce water without leftover molecules.
It is not possible to produce water without leftover molecules.
The equation will produce three molecules of water.
The equation will produce three molecules of water.
The result of the equation will be the same.
The correct statement is: Each oxygen molecule will combine with 2 hydrogen molecules with no leftover molecules.
The equation 2H2 + 1O2 →→ 2H2O represents the reaction between hydrogen gas (H2) and oxygen gas (O2) to produce water (H2O).
If we change the 2H2 to 3H2 molecules, the balanced equation becomes 3H2 + 1O2 →→ 2H2O.
From this balanced equation, we can conclude that the statement "The equation will produce three molecules of water" is correct.
To balance the equation, we need to ensure that there is an equal number of atoms of each element on both sides of the equation.
Initially, we have:
2H2 + 1O2 → 2H2O
If we change 2H2 to 3H2, the equation becomes:
3H2 + 1O2 → 2H2O
Now, let's count the number of atoms of each element on both sides:
On the left side, we have:
3 (atoms of hydrogen) x 2 (molecules of H2) = 6 atoms of hydrogen
1 (atom of oxygen) x 2 (molecules of O2) = 2 atoms of oxygen
On the right side, we have:
2 (atoms of hydrogen) x 2 (molecules of H2O) = 4 atoms of hydrogen
2 (atoms of oxygen) x 2 (molecules of H2O) = 4 atoms of oxygen
To balance the equation, we need to have an equal number of atoms of each element on both sides. Since we have 6 atoms of hydrogen on the left and only 4 atoms of hydrogen on the right, we can see that the equation is not balanced.
Therefore, the statement "It is not possible to produce water without leftover molecules" is correct.
