ammonia (NH3) dissolves in water (H2O) to form ammonium hydroxide (NH4OH)
This is an exothermic reaction.
It is an exothermic reaction. There are multiple ways to think about this. The reactants are in the gas phase and thus have a lot of energy within the molecules. When they react to produce a liquid, which has much less energy in its molecules. The energy must be released to the environment to lower the energy of the bonds.
the reaction is OH ç CH3 CH = CH CH2 CH3 + 2 H2O ® CH3 CH CH CH2 CH3 ç OH
Ammonium (cation): NH4+ Hydroxyl (anion): OH- It is incorrect to write NH4OH solution, because the solution is of ammonia (NH3) in water.
Exothermic
No. It is endothermic because it absorbs energy.
H2O + Na2SO4 = Exothermic reaction
Exothermic. Carbohydrates + oxygen (from respiration) yields CO2, H2O and heat.
Decomposition
exothermic, because the water (H2O) was a liquid, heat had to have been taken out to make Ice (H2O) solid. Hope this helps!!
Neutralisation reaction will take place. HCl + NaHCO3 ---> NaCl + H2O + CO2
36oC
NH4NO3 > H2O + N2O This isn't balanced.

The chemical reaction is:C6H5COOH + NH4OH = C6H5COONH4 + H2O
NH4OH < == > NH3 + H2O, it is a weak base
