7) According to your lab procedure, identify the chemicals necessary to produce NH3(g).
Write a net ionic equation for the generation of NH3(g).

Explanation:

Chemicals to produce NH₃ ( ammonia )

1 ) Ammonium chloride ( NH₄Cl )

2 ) Calcium hydroxide  Ca(OH)₂

2NH₄Cl + Ca(OH)₂ = CaCl₂ + 2NH₃ + 2H₂O.

Net Ionic equation

2NH₄⁺ ( aq ) + 2OH⁻ (aq )  = 2NH₃(g)  + 2H₂O .

definition

                    entropy is a measure of the randomness or the extent of disorder of a chemical process.

                      enthalpy is a measure of the heat change of a reaction occurring at a constant pressure.

measurement units:

                        entropy is measured in joule per kelvin (jk⁻¹)   whereas enthalpy is measured in joule per mole (jmol⁻¹)

requirements:

                            entropy has no requirements or limits, and its change is measured by the division between the heat change of the chemical process and the temperature.

                              in contrast, enthalpy can only be related to the heat change of the reaction under standard conditions.
