What is the enthalpy and entropy change when ammonium chloride is dissolved in water?
The published value for an enthalpy change is 14.78 kJ/mol
What is the chemical equation for ammonium nitrate decomposes into nitrogen and water?
When ammonium nitrate (NH4NO3) is mixed with water, the dissolution of ammonium nitrate occurs - that is, it is broken up into its ions. This is endothermic, and is the driving reaction behind instant cold packs.
If the solubility of KHT Potassium bitartrate increases with temperature increase what can you say about the sign of enthalpy change of the dissolution of KHTWhy?
Then the dissolution must be an endothermic process, as the heightening of the temperature will result in a greater accessibility to energy. The sign will be positive.
Is calcium nitrate plus ammonium hydroxide a physical change?
No, it is a chemical change. Rearrangement of atoms to make different compounds is one way to define a chemical reaction.
Is dissolution of sulfur in carbon disulphide is chemical or physical change?
physicl change

Does ammonium chloride and water is a chemical or a physical change?
Dissolution is a chemical process.

Is copper (2) nitrate and ammonium hydroxide a physical change?
No. It is a chemical change (chemical reaction) in which the products are different from the reactants. The balanced chemical equation is Cu(NO3)2+2NH4OH-->Cu(OH)2+2NH4NO3, which means one mole of copper(II) nitrate plus two moles of ammonium hydroxide produce one mole of copper(II) hydroxide plus two moles of ammonium nitrate.

Then the dissolution must be an endothermic process, as the heightening of the temperature will result in a greater accessibility to energy. The sign will be positive.
Why not use in ocean to change path of hurricane ammonium nitrate when mixed with water ammonium can turn itself cold?
it may kill many sea animals and it poisons the water.
What is relation between hydration energy lattice energy and enthalpy of solution?
enthalpy change of solution=enthalpy change of hydration - enthalpy change of lattice
What is the difference between enthalpy change and enthalpy change per mole?
Enthalpy is the energy absorbed or lost from a reaction, but enthalpy change per mole is the amount of energy lost per mole, so in order to get the overall enthalpy from the change per mole, you must multiply that value by the amount of moles used in the reaction.
Is calcium nitrate plus ammonium hydroxide a physical change?
No, it is a chemical change. Rearrangement of atoms to make different compounds is one way to define a chemical reaction.
How does the presence of a catalyst affect the enthalpy change of a reaction?
The presence of a catalyst affect the enthalpy change of a reaction is that catalysts do not alter the enthalpy change of a reaction. Catalysts only change the activation energy which starts the reaction.
What is molar enthalpy change?
Molar bond enthalpy shows the change in a bond association. For example, if one mole of bond is broken, the energy change that results is DHd (degree).
What is to change from solid to a gas and vice versa?
Enthalpy of Vaporization and Enthalpy of Condensation.
