A sample of natural gas containing 80% methane (CH‚ÇÑ) and rest nitrogen (N‚ÇÇ) is burnt with 20% excess air. With 80% of the combustibles producing CO‚ÇÇ and the reminder going to CO, the Orsat analysis in volume percent is$?

A. CO‚ÇÇ : 6.26, CO : 1.56, O‚ÇÇ : 3.91, H‚ÇÇO :15.66, N‚ÇÇ : 72.60
B. CO‚ÇÇ : 7.42, CO : 1.86, O‚ÇÇ : 4.64, N‚ÇÇ:86.02
C. CO‚ÇÇ : 6.39, CO : 1.60, O‚ÇÇ : 3.99, H‚ÇÇO:25.96, N‚ÇÇ:72.06
D. CO‚ÇÇ : 7.60, CO : 1.90, O‚ÇÇ : 4.75, N‚ÇÇ : 85.74
Answer» C. CO‚Äö√á√á : 6.39, CO : 1.60, O‚Äö√á√á : 3.99, H‚Äö√á√áO:25.96, N‚Äö√á√á:72.06
