Question

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) the equation will produce three molecules of water. it is not possible to produce water without leftover molecules. each oxygen molecule will combine with 2 hydrogen molecules with no leftover molecules. the result of the equation will be the same.

Explanation:

Step1: Write the new un - balanced equation

The new un - balanced equation is $3H_2+O_2
ightarrow H_2O$.

Step2: Balance the equation

To balance the hydrogen atoms, if we have 3 $H_2$ molecules (6 hydrogen atoms), we need 3 $H_2O$ molecules. To balance the oxygen atoms, since 3 $H_2O$ molecules have 3 oxygen atoms, we need $\frac{3}{2}O_2$ molecules. The balanced equation is $3H_2+\frac{3}{2}O_2
ightarrow3H_2O$ or $6H_2 + 3O_2
ightarrow6H_2O$. When we have 3 $H_2$ molecules reacting with oxygen to form water, we will produce 3 molecules of water.

Answer:

The equation will produce three molecules of water.
