Answer:
Pressure difference = 16.9 torr
Explanation:
The formula to be used since their is a difference in water level in the beaker and burette is;
Atmospheric pressure = pressure of gas in burette + pressure of water
Atmospheric pressure - gas pressure = pressure of water
Therefore, the difference between atmospheric pressure and gas pressure can be seen to be the pressure of the water
The pressure of water in mmHg = 23 cm H20 = 230 mmH2O
To convert to mmHg, we have to divide by 13.6 since mercury is 13.6 times heavier than water.
Pressure of water = 230 mmH2O * (1 mmHg/13.6 mmH20) = 16.9 mmHg
Since I mmHg = 1 torr, therefore,
Pressure difference = 16.9 torr
3 valence electrons are transferred in the formation of the compound potassium nitride because nitrogen needs 3 valence electron to become stable, or to have the electron configuration of noble Gases.
