A student performs an experiment to determine the melting point of ice in order to investigate the strength of electrostatic forces between its molecules. Once the student completes the experiment, which additional action should the student take? A) The student should perform multiple trials of the same experiment, then use the result closest to 0ºC.

B) The student should perform experiments using different amounts of ice, then take the average of all of the results.

C) The student should perform multiple trials of the same experiment, then take the average of all of the results.

D) The student should perform experiments using different amounts of ice, then use the result closest to 0ºC.

your answer would be “dry”

answer is: naturally occurring solid, inorganic compound or element is mineral.

minerals usually have crystalline form, that means than crystal constituents (atoms, molecules or ions) are arranged in a highly ordered microscopic structure, forming a crystal lattice that extends in all directions.

for example magnetite is a mineral of iron oxide (fe₂o₃).

calcite is a carbonate mineral and the most stable polymorph of calcium carbonate (caco₃).

dolomite is an   carbonate mineral composed of calcium magnesium carbonate (camg(co₃)₂).

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.
