Answer the following questions for this equation: 2 H2 + O2 --&gt; 2 H2O
laiz [17]

Answer:

                       1 Mole O₂ / 2 Mole H₂O

Explanation:

                  The balance chemical equation for the synthesis of water is as follow,

                                             2 H₂ + O₂ → 2 H₂O

In this equation the moles are specified by the coefficients i.e.

2 moles of H₂ reacting with 1 mole of O₂

2 moles of H₂ producing 2 moles of H₂O

1 mole of O₂ producing 2 moles of H₂O

Hence the molar ratio for O₂ and H₂O can be written as,

                            1 Mole O₂ : 2 Mole H₂O

or,

                           1 Mole O₂ / 2 Mole H₂O
