Describe each step of the copper cycle with regard to the five chemical reactions. Describe the obvious physical changes that occurred and relate them to the chemical changes that copper underwent during each step. Explain why some copper compounds formed precipitates in this experiment while others remained in solution. Why was it necessary to perform Reaction 1 in a fume hood

first one is the correct answer

what are the statements

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.

answer: mole of the gas

answer: mole of the gasexplanation:
