The chemical reaction is:
BaCl2 + 2 KOH ----------> Ba(OH)2 + 2 KCl
BaO2 + 2HCl -> BaCl2 + 2H2O
The formula unit for the formation of potassium chloride and barium sulfate is one mole. One unit of potassium sulfate and barium chloride are required for the reaction.
Potassium hydroxide
The chemical reaction between barium hydroxide and ammonium chloride to form barium chloride, ammonia and water is characterised by a change in temperature (which is fall in temperature). It is a endothermic reaction (which means heat absorbing reaction). Ba(OH)2 + NH4Cl ------------> BaCl2 + NH3 + H2O
barium hydroxide
BaCl2 + K2SO4 = BaSO4 + 2 KCl .
It forms a precipitate called sodium chloride and barium hydroxide, which both are colourless.
The formula unit for the formation of potassium chloride and barium sulfate is one mole. One unit of potassium sulfate and barium chloride are required for the reaction.
The answer is 1.24 kilojoules is absorbed in the reaction of 4.88g of barium hydroxide octahydrate with ammonium chloride. Kilojoule can be abbreviated as kJ.
Potassium hydroxide
The chemical reaction between barium hydroxide and ammonium chloride to form barium chloride, ammonia and water is characterised by a change in temperature (which is fall in temperature). It is a endothermic reaction (which means heat absorbing reaction). Ba(OH)2 + NH4Cl ------------> BaCl2 + NH3 + H2O
barium hydroxide
BaCl2 + K2SO4 = BaSO4 + 2 KCl .
6.37 g
2NH4Cl + Ba(OH)2 ---> BaCl2 + 2NH3 + 2H2O
Potassium and chloride ions.
The precipitate will be barium sulfate. The reaction is as follows:BaCl2(aq) + Na2SO4(aq) ==> 2NaCl(aq) + Ba(SO4)(s)
K2CrO4 + BaSo4 ----------> BaCrO4 (Precipitate) + K2SO4 Potassium Barium Barium Potassium Chromate Sulphate Chromate Sulphate It Is A Double Displacement Reaction
