Ca(OH)2 + NH4Cl --> NH3 + CaCl2 + H2O
i went at it for a whiile...and still can't get it...maybe the equation is wrong....well...ist from:
The slaked lime (Ca(OH)2) is added to the aqueous ammonium chlroide to produce ammonia, aqueous calcium chlrodie and water...

Balance
Ca(OH)2 + NH4Cl --> NH3 + CaCl2 + H2O
If you can't figure it out intuitively use a systematic approach.
Calcium appears in only one place on each side of the equation and in equal amounts so those two coefficients have to be the same. Use k.
kCa(OH)2 + NH4Cl --> NH3 + kCaCl2 + H2O
Chorine appears in only one place on each side of the equation but twice the amount on the right as on the left.
k*Ca(OH)2 + 2k*NH4Cl --> NH3 + k*CaCl2 + H2O
Now balance nitrogen. It appears only once on each side.
k*Ca(OH)2 + 2k*NH4Cl --> 2k*NH3 + k*CaCl2 + H2O
Now balance oxygen. It only appears once on each side.
k*Ca(OH)2 + 2k*NH4Cl --> 2k*NH3 + k*CaCl2 + 2k*H2O
Check to make sure hydrogen balances.
2 + 2*4 = 2*3 + 2*2
10 = 10
Set k = 1 and we have:
Ca(OH)2 + 2NH4Cl --> 2NH3 + CaCl2 + 2H2O

Ca(OH)2 + 2NH4Cl --> 2NH3 + CaCl2 + 2H2O
That looks right.

And now my answer:
Ca(OH)2 + 2NH4Cl --> 2NH3 + CaCl2 + 2H2O
That looks right also for me. Tks Awesome!
