A cylinder with a piston holds 3.50 moles of a diatomic gas. The gas in the cylinder absorbs 875 J of energy due to the higher t

emperature of the environment. At the same time, the cylinder expands to a larger volume, doing 112 J of work on the environment. (a) What is the change in internal energy of the gas in the cylinder (in J)

The change in the internal energy of the gas in the cylinder is 763 J

From the first law of thermodynamics, the change in internal energy(U) of a system is equivalent to the difference between net heat transfer(Q) into the system and the net work done(W) on the system

The equation for the change in the internal energy from the first law of thermodynamics is:

ΔU = ΔQ - ΔW

ΔU = 875 J - 112 J

ΔU = 763 J

Describe what happens on the molecular level when acetic acid dissolves in water.
kompoz [17]

Since most acetic acid molecules do not dissociate when a sample is dissolved in water, acetic acid and water molecule interactions are what determine how soluble a substance is. In its liquid state, water forms a network of hydrogen bonds among its molecules; when a material dissolves in water, this network of hydrogen bonds is broken.

<h3>What is acetic acid such a poor electrolyte?</h3>

Since acetic acid is a weak acid, only a small portion of the acetic acid molecules react to produce ethanoate and hydronium ions, shifting the equilibrium position substantially to the left. Aqueous acetic acid is a weak electrolyte as a result of the existence of these few ions.

<h3>Why does acetic acid have a low conductivity?</h3>

The majority ($> 99%) of the acetic acid molecules remain after dissolution, with only a very tiny portion deprotonating to form acetate anions. Only the latter are charged compounds, and as a result, only these increase the conductivity of the solution. They are few, and conductivity is low.

<h3>What makes acetic acid more potent than water?</h3>

The equilibrium shifts to the left and the concentration of hydrogen ions decreases when a strong acid is added to the buffer solution. A strong base is also added, which causes the equilibrium to move to the left and results in a smaller pH increase. Because of this, acetic acid is a better buffer than water.
