Detailed Solution

(a)	$\begin{array}{l} 2 C O + O_{2} \to 2 C O_{2} \\ 2 x x \\ O O 2 x \end{array}$
(b)	$\begin{array}{l} C H_{4} + 2 O_{2} \to C O_{2} + 2 H_{2} O (l) \\ 10 m l 30 m l \\ O 10 m l 10 m l 20 m l \end{array}$
(c)	$\begin{array}{l} N_{2} + 3 H_{2} \to 2 N H_{3} \\ 3 x x 0 \\ (3 x - \frac{x}{3}) 0 \frac{2}{3} x \end{array}$
(d)	$\begin{array}{l} N_{2} + 3 H_{2} \to 2 N H_{3} \\ x 3 x \\ 0 0 2 x \end{array}$
