A) If 115mL of 1.3 mol/L barium nitrate reacts with 150mL of 0.95 mol/L lithium sulfate, determine the concentration of the barium and lithium ions in the final
solution. (8 marks)

od double displacement reaction that could be used in

since electrons are negative the answer is neagtaive

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.
