A sample consisting of 1.00 mol of Argon is expanded isothermally at 273.15 K from 22.4 L to 44.8 L. Calculate DH, w, and q assuming Argon is an ideal gas and the expansion process is: (a) reversible (b) irreversible, against a constant external pressure equal to the final pressure of the gas (c) irreversible, against zero external pressure (i. e., free expansion) Answer in kJ.

answer; /// the amount of material dissolved in a measure of liquid(concentration) the above statement is (true); /// good luck

the potential energy of the reactants is 200j.

from the energy diagram, the energy of the product formed is 350j; this means that, this reaction is an endothermic reaction, because it absorbs energy from its environment.

d) a person who learns about the world by observing it.

explanation:

scientist are people who discover why and how things are done and made in the world.
