1 answer:
The sample of oxygen gas was collected through water displacement. So, the gas collected will be a mixture of oxygen and water vapor.
Given that the total pressure of the mixture of gases containing oxygen and water vapor = 749 Torr
Vapor pressure of pure water at =25.81mmHg
=
According to Dalton's law of partial pressures,
Total pressure = Partial pressure of Oxygen gas + Partial pressure of water
749 Torr = Partial pressure of Oxygen gas + 25.81 Torr
Partial pressure of Oxygen gas = 749 Torr - 25.81 Torr = 723.19 Torr
Therefore the partial pressure of Oxygen gas in the mixture collected will be 723.19 Torr

<em>Calculate the pH of the following substances formed during a volcanic eruption: </em>
<em>• Acid rain if the [H +] is 1.9 x 10-5 </em>
<em>• Sulfurous acid if [H +] = 0.10 </em>
<em>• Nitric acid if [H +] = 0.11</em>

<h3>Further explanation </h3>pH is the degree of acidity of a solution that depends on the concentration of H⁺ ions. The greater the value the more acidic the solution and the smaller the pH.
pH = - log [H⁺]
- pH acid rain
- pH Sulfurous acid
- pH Nitric acid
