\(CNG\) is an important transportation fuel. When \(100 \,g\) \(CNG\) is mixed with \(208\) 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]
- A \(143\)
- B \(134\)
- C \(167\)
- D \(189\)
Answer & Solution
Correct Answer
(A) \(143\)
Step-by-step Solution
Detailed explanation
\(CH _{4}+2 O _{2} \rightarrow CO _{2}+2 H _{2} O\) Mole \(\frac{100}{16} \quad \frac{208}{32}\) \(= 6.25\quad=6.5\) \(\frac{\text { Mole }}{\text { Stoi. Coeff. }} \frac{6.25}{1} \quad \frac{6.5}{2}=3.25\) So, \(O _{2}\) is limiting reagent Mole-Mole analysis…
