Write the balanced equation for the preparation of NH3 from ammonium chloride and calcium hydroxide.
(a) Calculate the mass fo ammonia that can be obtained from 21.4 g of NH4Cl by the reaction: 2NH4Cl+Ca(OH)2→CaCl2+2H2O+2NH3 (b) what will be ht volume of ammonia when measured at STP?
The secondary reactions which takes place in dry cell are:
1)MnO2+NH+4+e−→MnO(OH)+NH3
2)2NH4Cl+2(OH−)→ 2NH3+2Cl−+ 2H2O
3) Zn+2MnO2→ [Zn(NH3)2]+2OH−+2MnO(OH)
4) Zn2+2NH3+2Cl−→ [Zn(NH3)2]Cl2 or ZnCl2.2NH3
Correct statements are:
Balance the following equation b hit and trial method :. NH4Cl + Ca(OH)2 ------------> CaCl2 + H2O + NH3
