The heat evolved in the combustion of methane is given as :
`CH_(4)(g) + 2O_(2)(g) to CO_(2)(g) + 2H_(2)O(l)`
`Delta_(r)H^(@) = 890.3 kJ`
Calculate :
(a) how many grams of methane would be required to produce 445.15 kJ of heat on combustion?
How many grams of `CO_(2)` would be formed when 445.15 kJ heat is evolved?
(c) what volume of `O_(2)` at S.T.P would be used in the above combustion process ?
