Given the incomplete equation for the combustion of ethane (C2H6) : 2 C2H6 + 7 O2 - -> 4 CO2 + 6 ___

H2O2

HCOOH

CH3OH

H2O

The answer to your question is: H2=

Explanation:

Reaction

2 C2H6 + 7 O2 - -> 4 CO2 + 6 ___

A combustion reaction, is a reaction where the reactants are a compound with carbon plus oxygen and the products will be carbon dioxide and water.

Then, in the reaction given the only product that is lacking is water (H2O).

2 C2H6 + 7 O2 - -> 4 CO2 + 6 H2O

Explanation:

All hydrocarbons undergo combustion reactions to form water (H2O) and Carbon dioxide (CO2) as the only products.

Among the options give, the correct product is H2O

The Correct equation is hence given as;

2 C2H6 + 7 O2 - -> 4 CO2 + 6 H2O
