Step 1

Given,

Mass of CH4 = 0.64 g

Mass of O2 = 4.4 g

Mass of CO2 produced = 1.07 g

Moles of CH4 and Br2 can be calculated as:

Step 2

The balanced chemical reaction of gaseous methane and oxygen gas to produce gaseous carbon dioxide and gaseous water can be written as:

CH4 (g) + 2 O2 (g) → CO2 (g) + 2 H2O (g)

Stoichiometric molar ratio of CH4 : O2 = 1 : 2

Actual molar ratio of CH4 : O2 = 0.04 : 0.1375 = 1 : 3.4

Therefore, O2 is present in excess and CH4 is the limiting reagent. Therefore, the theoretical moles of CO2 produced will depend on CH4.

From the given reaction, it is evident that :

Step 3

Theoretical mass of CO2 produced c...
