When performing an extraction, venting of the vessel should be done almost immediately after initial mixing. This often results

in the release of a gas (pressure). After subsequent mixing, each venting releases less gas, so venting does not need to be done as frequently. What is the gas (pressure) that is being released during venting? Why does the gas form and why?

A certain metal M forms a soluble sulfate salt M2SO4. Suppose the left half cell of a galvanic cell apparatus is filled with a 5
VikaD [51]

Answer:

Right

Explanation:

The given parameters are;

The soluble sulfate formed by the metal, M = M₂SO₄

In the galvanic cell formed by the metal M, we have;

The concentration of M₂SO₄ in the left half cell = 50.0 mM = 0.05 M

The concentration of M₂SO₄ in the right half cell = 5.00 M

In the galvanic cell, the metal 'M' will be dissolved into the solution with lower concentration as M²⁺ which is the left half cell, making the cell negative and the solution more concentrated

In the right half cell, the metal 'M²⁺' in the solution will be plated unto the electrode making the solution less concentrated and the electrode in the right half cell will be the positive electrode

Therefore;

The electrode which will be positive is the electrode in the right half cell.

Rank the compounds CH3OH CH3CH2OH CH3CH2CH2OH in terms of increasing evaporation rate. 1. CH3CH2CH2OH < CH3CH2OH < CH3OH 2
Artemon [7]

Answer: Option (5) is the correct answer.

Explanation:

It is known that more is the number of carbon atoms linearly present in a compound more will be its boiling point. This is because then more number of intermolecular forces are present within the atoms of a compound.

Hence, lesser is the number of carbon atoms present less will be the intermolecular forces present in it. Therefore, more readily the compound will evaporate into the atmosphere.

Thus, we can conclude that given compounds are ranked in increasing rate of evaporation as follows.

      CH_{3}CH_{2}CH_{2}OH < CH_{3}CH_{2}OH[/tex] < CH_{3}OH
