In general, what is the effect of increased temperature on the solubility of a gas?

Chemistry

Alecsey [184]3 years ago

The physical explanation is that increasing temperature increases the kinetic energy of the gas molecules. Hence, their random motion breaks more intermolecular bonds and the gas is less dissolved in the solvent. In contrast, solid solutes in water have increased solubility with increased temperatures.

If an atom has 8 protons. How many electrons does it have? What is the atoms charge?
Juli2301 [7.4K]
The amount if protons is the same as the amount of electrons, so it would be 8. The charge is -2. Look at oxygen in the periodic table.

You were making a cream based sauce for your pasta and decided to add some freshly canned tomatoes to the sauce. It tasted fine,
soldier1979 [14.2K]

Answer & explanation:

Canned fruits and vegetables generally have a high acidity and salinity content, in order to prevent the product from spoiling, in addition to enhancing its flavor.

The cream-based sauce started to curdle due to the acidity present in the canned tomatoes.

By lowering the pH of dairy products, a protein in them called casein begins to clot. It is this clotting of the casein that causes the cream-based sauce to curdle.

the heat of fusion of acetone is 5.7 kJ/mol. Calculate to two significant figures the entropy change when 6.3 mol of acetone mel
shtirl [24]

<u>Answer:</u> The entropy change of the process is 2.0\times 10^2J/K

<u>Explanation:</u>

To calculate the entropy change for different phase at same temperature, we use the equation:

\Delta S=n\times \frac{\Delta H_{f}}{T}

where,  

\Delta S = Entropy change

n = moles of acetone = 6.3 moles

\Delta H_{f} = enthalpy of fusion = 5.7 kJ/mol = 5700 J/mol    (Conversion factor:  1 kJ = 1000 J)

T = temperature of the system = -94.7^oC=[273-94.7]=178.3K

Putting values in above equation, we get:

\Delta S=\frac{6.3mol\times 5700J/mol}{178.3K}\\\\\Delta S=201.4J/K=2.0\times 10^2J/K

Hence, the entropy change of the process is 2.0\times 10^2J/K
