KB = [NH4+].[OH-] divided by [NH3] in case of equilibrium. All concentrations are IN watery (aq) dilution.
KB = 1.7*10-5 (at 25 oC)
NH3 is a weak base (equilibrium more at the left than to the right side of the reaction equation: symbolized as <<==> ) NH3 + H2O <<==> NH4+ + OH-
The given chemical equation shows a neutralization reaction. In this reaction, an acid (HCl) reacts with a base (NH3) to form a salt (NH4Cl) and water.
The conjugate base of NH3 is NH2-, formed by removing a proton (H+) from NH3.
The conjugate base of NH3 is NH2-.
The name of the common base NH3 is ammonia.
NH3 is a weak base (equilibrium more at the left than to the right side of the reaction equation: symbolized as <<==> ) NH3 + H2O <<==> NH4+ + OH-
NH4OH < == > NH3 + H2O, it is a weak base

In this case, this is an acid-base reaction between nitric acid and ammonia. Nitric Acid is a strong acid, therefore, its hydrogen atom dissociates completely. The equation looks like this:HNO3(aq) + NH3(aq) => NH4NO3(aq)
The name of the common base NH3 is ammonia.
The chemical equation for aqueous ammonia (NH3) in water is NH3 + H2O -> NH4+ + OH-.
So NH4Cl(s) -----> NH4+(aq) + Cl-(aq). As NH4Cl is ionic you can assume it is a solid. Since H2O is polar it reacts with the NH4Cl ion in a way which allows it to dissociate the ion. The oxygen is slightly negative while the hydrogens have a partial positive charge. The negativity of the oxygen in H2O causes the positive charge of the NH4+ molecule to cancel making it no longer attracted to the Cl. The hydrogen in H2O will do the same to the Cl. Once this happens you will have the products stated above in the reaction equation. NH4+ will further react with the water. NH4+ + H2O ---> NH3 + H3O+ . H3O+ is produced rather than OH- because NH4+ is acidic and therefore will donate a hydrogen. Note that because NH4Cl fully dissociates, you do not add in the + H2O in the first equation.
3N2H4 --> 4NH3 + N2 is the correctly balanced equation.
The balanced equation for the reaction between copper sulfate (CuSO4) and ammonia (NH3) is CuSO4 + 4NH3 → Cu(NH3)4SO4.
The chemical equation for the formation of ammonia is N2 + 3H2 → 2NH3. This equation represents the reaction between nitrogen gas (N2) and hydrogen gas (H2) to produce ammonia (NH3). The balanced equation shows that one molecule of N2 reacts with three molecules of H2 to form two molecules of NH3.
