The transformation occurring in Duma's method is given below C_2 H_7 N +(2 x+y/2) CuO → x CO_2+y/2 H_2 O +z/2 N_2+(2 x+y/2) Cu The value of y is \ \…
The transformation occurring in Duma's method is given below
$$\mathrm{C}_2 \mathrm{H}_7 \mathrm{~N}+\left(2 x+\frac{y}{2}\right) \mathrm{CuO} \rightarrow x \mathrm{CO}_2+\frac{y}{2} \mathrm{H}_2 \mathrm{O}+\frac{z}{2} \mathrm{~N}_2+\left(2 x+\frac{y}{2}\right) \mathrm{Cu}
$$
