Phương trình để điều chế NH3 trong phòng thí nghiệm là:
A.$$2N{H_4}Cl + Ca{(OH)_2}\buildrel {{t^0}} \over \longrightarrow CaC{l_2} + 2N{H_3} + 2{H_2}O$$
B.$${N_2}{\rm{ }} + {\rm{ }}2{H_2}{\rm{ }}{\rm{ }}2N{H_3}$$
C.$$N{H_4}C{l_{(r)}}\buildrel {{t^0}} \over
\longrightarrow N{H_3}_{(k)} + HC{l_{(k)}}$$
D.$$N{H_4}HC{O_{3(r)}}\buildrel {{t^0}} \over \longrightarrow N{H_3} \uparrow + C{O_2} \uparrow + {H_2}O \uparrow $$
