Question

Answer the following questions for this equation: 2 H2 + O2 --> 2 H2O

c. What is the 02 / H20 molar ratio? (ANSWER IN THE FORM OF XY

Answer 1

1 Mole O₂ / 2 Mole H₂O

Step-by-step 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
