Write the net ionic equation for the following reaction:

AgC2H3O2(aq) + CaCl2(aq) →

2Ag^+(aq) + 2Cl^-(aq) > 2AgCl(s)

Explanation:

The net ionic equation reflects the main reaction that occurred in the system. It tells you the most important reaction that took place.

If we first put down the balanced molecular equation for the reaction, we have;

CaCl2(aq) + 2 AgC2H3O2(aq) > 2 AgCl(s) + Ca(C2H3O2)2 (aq)

The net ionic equation is;

2Ag^+(aq) + 2Cl^-(aq) > 2AgCl(s)

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.
