Asample of oxygen gas is collected over water at 22°c and 98.67 kpa pressure. if the partial pressure of the water is 2.67 kpa, the partial pressure of the oxygen is?

Explanation:

The law of partial pressures states that, in a mixture of gases, the total pressure of the mixture is equal to the sum of the individual pressures of each gas, as if each gas were alone in the mixture.

So:

your answers are a,b,,e and f

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.
