The distance between two bonded atoms (the bond length), is usually in units of picometers, where 1.00 m = 1.00 x 1012 pm (or 1.00 pm = 1.00 x 10-12 m). What is the distance between two carbon atoms, in units of miles, if the bond length is 121 pm?

the ratio of the conjugate base to the acid required to attain the desired ph.

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.

it is stable as it is in group 0 which have full outer shells of electrons
