Give an example of each of the following: (a) a monatomic cation, (b) a monatomic anion, (c) a polyatomic cation,(d) a polyatomic anion.

Answer and Explanation:

(a) MONATOMIC CATION: Monatomic cation are those cation in which only one atom is present

Example :

(b) MONATOMIC ANION : Monatomic anion are those cation in which only one atom is present

Example :

(C) Polyatomic Cation : Polyatomic cations are those cation which contains more than one atom

Example :

(C) Polyatomic Anion  : Polyatomic anions are those cation which  contains more than one atom

Example :

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.
