What is the difference between relative and absolute dating. what is radiometric dating. how do scientists use half-life to determine the age of fossils. how many rocks are on earth. when is the earth’s birthday. what is does isotope mean. what does radiometric dating mean.

ONe ur not all into. romantic dating ur into. they prosses it with how old the malucules are . 3.8 B . every 365 days from 1/1/whenever at mid night 12:00AM. a method of dating geological or archeological specimens by determining the relative proportions of particular radioactive isotopes present in a sample.

Explanation:e.

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.
