What mass of carbon dioxide, co2(g), in g, is produced when 5.0 g of calcium carbonate, caco3 (s), reacts completely with hydrochloric acid, HCl (aq)? CaCO3 (s) + 2 HCI (aq) → CaCl2 (aq) + H2O (l) + CO2 (g)

take a better picture and ill do it

false

because it does not have the potential to be entirely used up

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.
