Question 4 Mide Choice Worth 2 points) A student wants to determine whether an unknown solid is an ionic compound. He puts some in water and finds that it does not dissolve. He says that this proves the
solid is ionic Which best evaluates the student's reasoning?
He is incorrect, because water can dissolve ionic solids
The test proves nothing, because water dissolves all solids
He is correct, because polar liquids cannot solve ionic solids
The test proves nothing, because it only shows that the solid is a compound.

a chemical reaction happens

explanation:

with this one i know the answer in craters one reason i looked it up and i learned about it there is my evidence

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.
