Solid potassium chloride is obtained by the reaction of chlorine gas and solid potassium . write a balanced chemical equation for this reaction.

Explanation:

A chemical equation that represents equal number of atoms on both reactant and product side is known as a balanced chemical equation.

For example, when chlorine gas reacts with solid potassium then a synthesis reaction takes place which leads to the formation of solid potassium chloride.

The reaction equation will be as follows.

Number of atoms on reactant side are as follows.

Cl = 2

K = 1

Number of atoms of product side are as follows.

Cl = 1

K = 1

Hence, to balance this chemical equation, multiply K on reactant side by 2 and multiply KCl by 2 on product side.

Therefore, the balanced chemical reaction equation will be as follows.

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.
