Question

Which equation would have the same coefficients in the same order as ₂CO₂ + 3H₂O → C₂H₆O + 3O₂?

1) FeCl3 + NH₄⁺OH → Fe(OH)3 + NH₄⁺Cl
2) CH₄ + O₂ → CO₂ + H₂O
3) Fe + H₂SO₄ → Fe₂⁺(SO₄)3 + H₂
4) PCl5 + H₂O → HCl + H₃PO₄

Answer 1

The equation that has the same coefficients in the same order as 2CO2 + 3H2O → C2H6O + 3O2 is CH4 + O2 → CO2 + H2O.

Step-by-step explanation:

The equation that has the same coefficients in the same order as 2CO2 + 3H2O → C2H6O + 3O2 is:

1. CH4 + O2 → CO2 + H2O

In both equations, there is one mole of the substance as the product, and the coefficients of the reactants may have to be fractional to balance the reaction.
