NaNO2 \(\rightarrow\) N2 \(\rightarrow\) Mg3N2 \(\rightarrow\) NH3 \(\rightarrow\) Cu \(\rightarrow\) Cu(NO3)2 \(\rightarrow\) Cu(OH)2 \(\rightarrow\) CuO

Answer 1

\(4NaNO_2\xrightarrow[]{t^o}2Na_2O+3O_2+2N_2\)

\(N_2+3Mg\xrightarrow[]{t^o}Mg_3N_2\\ Mg_3N_2+6H_2O\rightarrow3Mg\left(OH\right)_2+2NH_3\)

\(2NH_3+3CuO\xrightarrow[]{t^o}3Cu+3H_2O+N_2\)

\(Cu+2AgNO_3\rightarrow Cu\left(NO_3\right)_2+2Ag\)

\(Cu\left(NO_3\right)_2+2KOH\rightarrow Cu\left(OH\right)_2+2KNO_3\)

\(Cu\left(OH\right)_2\xrightarrow[]{t^o}CuO+H_2O\)

Answer 2

(1) \(NaNO_2+NH_4Cl\xrightarrow[]{t^\circ}N_2\uparrow+2H_2O+NaCl\)

(2) \(3Mg+N_2\xrightarrow[]{t^\circ}Mg_3N_2\)

(3) \(Mg_3N_2+6H_2O\rightarrow3Mg\left(OH\right)_2\downarrow+2NH_3\uparrow\)

(4) \(2NH_3+3CuO\xrightarrow[]{t^\circ}3Cu+2N_2\uparrow+3H_2O\)

(5) \(3Cu+8HNO_3\text{ (loãng)}\rightarrow3Cu\left(NO_3\right)_2+2NO\uparrow+4H_2O\)

(6) \(Cu\left(NO_3\right)_2+2LiOH\rightarrow Cu\left(OH\right)_2\downarrow+2LiNO_3\)

(7) \(Cu\left(OH\right)_2\xrightarrow[]{t^\circ}CuO+H_2O\uparrow\)
