Question

What is the ratio of molecules in:
CH4 + 2O2 -> CO2 + 2H2O

Answer 1

1:2:1:2

Step-by-step explanation:

A molecule is made up of aggregates of small particles called atoms.

CH₄ + 2O₂ → CO₂ + 2H₂O

From the reaction above we have: 1 molecule of methane CH₄ reacting with 2 molecules of oxygen gas O₂ to produce 1 molecule of carbon dioxide gas CO₂ and 2 molecules of H₂O:

CH₄ + 2O₂ → CO₂ + 2H₂O

1 : 2 : 1 : 2
