Let 16.2 grams of aluminum completely react with HCl solution a) Write the equation for the reaction
b) Calculate the volume of H2 gas produced at dtc
c) If the above volume of H2 is used to reduce 58 grams of Fe3O4, which substance is left over after the reaction and how many grams are left over?
d) Calculate the mass of Fe produced.

c- cold periods in earth's history during which glaciers covered much of the surface.

explanation:

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.
