A scientist measures in seconds the amount of time it takes for solution to completely dissolve. he gathers these measurements from multiple trials: 5,5,5,6,6,7,7
what would be the best way for him to report the centre of the data
A. By reporting the mode
B. By reporting the median
C. By reporting the mean absolute deviation
D. By reporting the interquartile range

B.

Explanation: the median is the middle of a set of numbers and i had the same question and i'm pretty sure that centre is supposed to be center. -_-

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.
