Sort each of the following events based on whether the solubility of the indicated gas will increase, decrease, or stay the same
STatiana [176]

The answers are: 1) decrease 2) increase 3) decrease 4) increase 5) increase

<h3>FURTHER EXPLANATION</h3>

The following factors affect the solubility of gases in liquids:

1. Temperature - inverse relationship

<em>As the temperature is increased, the gas particles gain energy and start to move faster. This enables them to escape the liquid leading to decrease in the solubility of the gas. </em>

2. Partial Pressure of gas - direct relationship

<em>According to Henry's Law, for a given temperature, the solubility of the gas and the partial pressure of the gas above the liquid are proportional. With the application of pressure on the gas above the liquid, the gas particles are forced to move into the solvent.</em>

<em />

1. Temperature is increased - gas solubility decreases (Factor 1)

2. Partial pressure of an anesthetic gas is increased - gas solubility increases  (Factor 2)

3. O2: temperature of a body of water rises - gas solubility decreases (Factor 1)

4. Pressure of a gas over a solvent is increased - gas solubility increases (Factor 2)

5. Air in blood: a diver descends 10 m and the pressure increase by 1 atm - gas solubility increases (Factor 2)

<em>As the diver goes deeper, the pressure increases and more gases dissolve in the diver's blood. As the diver ascends, he or she must do so slowly to ensure that this large amount of gas is removed from the blood gradually otherwise, the diver might suffer from decompression sickness.</em>

Which element in period 4 has the highest electronegativity?
sashaice [31]
It will be K-potassium because when you go down a group the electronegativty gets bigger while when you go across the period they get smaller because of the valence electrons. Group 8 has the lowest electronegativty because they have a full outer shell. From left to right on the periodic table it decreases but from top to bottom it increases.
