PLEASE HELP ME Which of the following is an example of -ΔS? Picking up marbles and placing them in a sack Paint spilling onto the floor from a can Grains of sand being dropped onto the carpet Dropping a drop of red dye into water

Picking up marbles and placing them in a sack

Explanation:

The entropy of a chemical system is defined as the measure of disorder. Therefore a negative change in entropy is the movement to a more ordered state. The only option here which achieves a more ordered state, would be the first option.

Picking up marbles and placing them in a stack achieves more order, rather than the other options - that achieve more disorder.

answers: to make sure that all of the broken pieces of tablet were added to the water, to allow for fair comparison of all three trials, with different particle sizes to avoid experimental error

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.
