Detailed explanation-1: -The oxygen atoms can be balanced by putting a 2 in front of the O2 on the left: CH4 + 2O2 CO2 + 2H2O. The equation is now balanced.
Detailed explanation-2: -CH 4 ( g ) Methane + 2 O 2 ( g ) Oxygen gas → CO 2 ( g ) Carbon dioxide + 2 H 2 O ( g ) Water vapours.
Detailed explanation-3: -Answer and Explanation: The products of the chemical reaction are CO2 C O 2 and H2O H 2 O . The given chemical equation shows the combustion reaction of methane. In a chemical equation, the arrow shows the direction of the reaction where it points to the product side (shows the products).
Detailed explanation-4: -Answer and Explanation: The answer is C) a combustion reaction. The given reaction is an example of a combustion reaction. Combustion reaction includes the Oxygen gas as a reactant and produces Carbon Dioxide and Water as a product.
