Methane combines with oxygen in the air to make carbon dioxide and water vapor. which of the chemical equations matches the reaction above? a. ch4 + 2o2 co2 + 2h2o b. c2h4 + 2o2 2co + 2h2o c. ch4 + 2co2 2co2 + 2h2o d. ch4 + 2o 2co + 2h2o

Answer : The correct option is, (A)

Explanation :

Balanced chemical reaction : It is defined as the number of atoms of individual elements present on reactant side must be equal to the product side.

As per question, when methane combines with oxygen then it react to give carbon dioxide and water vapor as a product.

Thus, the balanced chemical reaction will be,

This reaction is known as combustion reaction in which a hydrocarbon react with oxygen to given carbon dioxide and water as product.
