Which type of chemical reaction takes place when barium hydroxide and ammonium chloride are mixed together in terms of heat released or absorbed?
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
What gas is created when you heat up sodium hydroxide solution and ammonium chloride solution?
Ammonia gas is created when you heat up a mixture of sodium hydroxide solution and ammonium chloride solution. This reaction is known as the ammonium chloride and sodium hydroxide reaction.
How can I effectively thicken a solution using ammonium chloride?
To effectively thicken a solution using ammonium chloride, you can dissolve the ammonium chloride in the solution and then heat it to evaporate the water, leaving behind a thicker solution.
What is the heat solution of calcium chloride?
The heat of solution for CaCl2 is -176,2 cal/g.
When 1 gram of zinc chloride ZnCl2 is dissolved in water the heat evolved is 0.53kJ Calculate the molar heat of substance of solution of zinc chloride?
To calculate the molar heat of solution of zinc chloride, we use the heat evolved by dissolving 1 gram of ZnCl2 in water. First, we convert the mass of ZnCl2 to moles using its molar mass of 136.3 g/mol. Then, we divide the heat evolved by the number of moles dissolved to get the molar heat of solution. In this case, the molar heat of solution would be 3.89 kJ/mol.
Use Hess's law to find the heat of solution when barium chloride is dissolved in water?
-14 kj
Is barium chloride in water endothermic or exothermic?
When barium chloride (BaCl₂) is dissolved in water, the process is endothermic. This means that it absorbs heat from the surroundings, resulting in a decrease in the temperature of the solution. The dissolution of barium chloride requires energy to break the ionic bonds, and this energy is greater than the heat released during the hydration of the ions.
Is the reaction between barium chloride and water endothermic or exothermic?
The reaction between barium chloride (BaCl₂) and water is endothermic. When barium chloride dissolves in water, it absorbs heat from its surroundings, resulting in a decrease in temperature of the solution. This is characteristic of endothermic reactions, where energy is absorbed rather than released.
What is the heat of solution for sodium chloride in joules assume that the specific heat capacity of the system is the same as that for water?
The standard enthalpy for the change in solution is: +3,87 kJ/mol at 25 0C
Why is the beaker coverd with watchglass when heating the combine solutions of barium chloride and sodium sulfate solution on a waterbath?
protect the heat effect from the sun
What is the heat of solution for lithium chloride?
- 37.1 kj/mol is the heat of solution for lithium chloride.

What chemical makes a firework green?
The chemical that makes a firework green is typically barium compounds, such as barium chloride or barium nitrate. When the firework is ignited, the heat causes the barium to emit green light.
What gas is created when you heat up sodium hydroxide solution and ammonium chloride solution?
Ammonia gas is created when you heat up a mixture of sodium hydroxide solution and ammonium chloride solution. This reaction is known as the ammonium chloride and sodium hydroxide reaction.
Take about 2 g barium hydroxide in a test tube. Add 1 g of ammonium chloride and mix with the help of a glass rod. Is this an exothermic or an endothermic reaction?
This is an endothermic reaction. When barium hydroxide and ammonium chloride are mixed, they react to form barium chloride, ammonia, and water. This reaction absorbs heat from the surroundings, causing a decrease in temperature.
How much heat in kilojoules is absorbed in the reaction of 4.88g of barium hydroxide octahydrate with ammonium chloride?
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.
When 1.0 mol 208.23 g of barium chloride is dissolved in 1000.0 g of water in a constant pressure calorimeter the temperature of the water rises from 20.0C to 22.2C What is the heat of solution?
-11000 J/mol
