Calculate the hydrogen-ion concentration [H+] for the aqueous solution in which [OH–] is 1 x 10–11 mol/L. Is this solution acidic, basic, or neutral? Show your work. (3 points) Use Kw to solve for the hydrogen ion concentration here. Then, once you have your numerical answer (with units!), answer the question about the solution. Calculate the hydrogen-ion concentration (show all set up work with calculations) – (2 pts)
Discuss your answer and how it is related to the solution being acidic, basic or neutral and then identify your solution as acidic, basic or neutral based on your calculated hydrogen-ion concentration. – (1 pts)

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.

i think its 5049.

i hope this !
