Question

Hoàn thành chuỗi phản ứng sau:

\(NH_3\xrightarrow[\left(1\right)]{+CuO,t^o}A\)(khí) \(\xrightarrow[\left(2\right)]{+H_2,xt,t^0}NH_3\xrightarrow[\left(3\right)]{+O_2,xt,t^0}C\xrightarrow[\left(4\right)]{+O_2}D\xrightarrow[\left(5\right)]{+O_2,H_2O}E\xrightarrow[\left(6\right)]{+NaOH}G\)

Answer 1

A: `N_2`

C: `NO`

D: `NO_2`

E: `HNO_3`

G: `NaNO_3`

\(\left(1\right)2NH_3+3CuO\underrightarrow{t^o}3Cu+N_2+3H_2O\)

\(\left(2\right)N_2+3H_2\underrightarrow{xt,t^o}2NH_3\)

\(\left(3\right)4NH_3+5O_2\underrightarrow{xt,t^o}6H_2O+4NO\)

\(\left(4\right)2NO+O_2\rightarrow2NO_2\)

\(\left(5\right)4NO_2+O_2+2H_2O\rightarrow4HNO_3\)

\(\left(6\right)HNO_3+NaOH\rightarrow NaNO_3+H_2O\)
