His main points are that everything is made of atoms, all atoms in an element are exactly the same, atoms are indivisible and cannot be destroyed, and atoms in different elements have different size and mass

Three moles of an ideal gas undergo a reversible isothermal compression at temperature 18.0 ?c. during this compression, an amou

Lena [83]

We calculate the entropy of an ideal gas follows:

For an isothermal compression, change in internal energy is equal to zero.
Thus, the heat added to the gas is equal to the work done on the gas which is given as 1750 J.

Entropy would be 1750/301 = 5.81 J/K

A gas with a volume of 4.0L at a pressure of 205kPa is allowed to expand to a volume of 12.0L. What is the pressure in the conta

mr Goodwill [35]

Answer:

68.3 kilo Pascal is the pressure in the container.

Explanation:

To calculate the new pressure , we use the equation given by Boyle's law. This law states that pressure is inversely proportional to the volume of the gas at constant temperature.

The equation given by this law is:

$P_1V_1=P_2V_2$

where,

$P_1\text{ and }V_1$ are initial pressure and volume.

$P_2\text{ and }V_2$ are final pressure and volume.

We are given:

$P_1=205kPa\\V_1=4.0 L\\P_2=?\\V_2=12.0 L$

Putting values in above equation, we get:

$P_2=\frac{P_1V_1}{V_2}$

$=\frac{205 kPa\times 4.0 L}{12.0 L}=68.3 kPa$

68.3 kilo Pascal is the pressure in the container.

When formic acid is treated with potassium hydroxide (KOH), an acid-base reaction occurs, forming a carboxylate ion. For the mec

Arturiano [62]

Answer:

See explanation

Explanation:

The reaction between formic acid and potassium hydroxide is an acid base reaction.

Remember that an acid base reaction yields salt and water only.

If you look at the curved arrow mechanism shown, you will discover that the hydroxide ion from KOH abstracts a proton from the acid to yield potassium formate and water
