CNG is an important transportation fuel. When 100 gCNG is mixed with 208 g oxygen in vehicles, it leads to the formation of CO 2 and H 2 O and produces large quantity of heat during this combustion, then the amount of carbon dioxide, produced in grams is [nearest integer] [Assume CNG to be methane]

Correct answer

0

Step-by-step solution

CH 4 +       2 O 2 ⟶       CO 2 + 2 H 2 O 100 16         208 32 Number   of   moles stoichiometric   coefficient   for   CH 4 = 6 . 25 1    Number   of   moles stoichiometric   coefficient   for   O 2 = 6 . 5 2 = 3 . 25 The reagent with lower ratio of number of moles to stoichiometric coefficient is called limiting reagent. Hence, O 2 is limiting reagent Limiting reagent decides the amount of product
