The composition of air by volume is approximately 1/5 oxygen, 4/5 nitrogen. when
air is passed through red-hot carbon, the following reaction occurs: 2c + o2(g)
2co(g). if all of the oxygen is converted to carbon monoxide, what is the
composition, by volume, of the gas produced?
(a)1/5 carbon monoxide, 4/5 nitrogen
(b) 1/3 carbon monoxide, 2/3 nitrogen
(c) 2/5 carbon monoxide, 3/5 nitrogen
(d)1/2 carbon monoxide, 1/2 nitrogen
