Explain why the relative atomic mass of chlorine on the periodic table is not a whole number.

This often takes place for other factors as nicely it is simply that chlorine and copper have values at roughly .5 between two different values so aren’t rounded. As you do greater complex chemistry you will begin using periodic tables with more unique masses.

This is now not the specific mass wide variety as I rounded the abundances of the isotopes to the nearest 5%. They are absolutely 75.78% and 24.44% and this gives a mass number of 35.45.

can you attach a picture of the lettuce? : )

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.
