Question

a) Write a chemical equation to prepare ammonia from ammonium chloride?
b) Write a chemical equation to identify $C{u}^{+2}$ & $A{g}^{+}$ ions with the application of $N{H}_3$?
c) Draw a labeled diagram showing flowchart for the manufacture of ammonia?

Answer 1

a) The chemical equation to prepare ammonia from ammonium chloride is
$2N{H}_{4}Cl+Ca(OH{)}_2\to CaC{l}_2+2H_{2}O+2N{H}_3\uparrow$
b) Chemical equations to identify Cu${}^{+2}$ & Ag${}^{+}$ ions with the application of NH${}_3$:
$AgCl+2N{H}_{4}OH\left(excess\right)\to \left[Ag\right(N{H}_3{)}_2]Cl+H_{2}O$
$CuS{O}_4+2N{H}_{4}OH\to Cu(OH{)}_2\downarrow +(N{H}_4{)}_{2}S{O}_4$
$Cu(OH{)}_2+4N{H}_{4}OH(excess)\to [Cu\left(N{H}_3{)}_4\right](OH{)}_2+4H_{2}O$
c) Flowchart for the manufacture of ammonia by Haber process is as shown.
$N_2+3H_2\rightleftharpoons 2N{H}_3$
