Answer : The enthalpy change of dissolution of is 54.3 kJ/mole
Explanation :
Heat released by the reaction = Heat absorbed by the calorimeter + Heat absorbed by the water
where,
q = heat released by the reaction
= heat absorbed by the calorimeter
= heat absorbed by the water
= specific heat of calorimeter =
= specific heat of water =
= mass of water = 107.70 g
= change in temperature =
Now put all the given values in the above formula, we get:
Now we have to calculate the enthalpy change of dissolution of
where,
= enthalpy change = ?
q = heat released = 1.1123 kJ
m = mass of = 2.84 g
Molar mass of = 138.55 g/mol
Therefore, the enthalpy change of dissolution of is 54.3 kJ/mole
Answer:
Nitrogen = 0.3 atm
Oxygen = 0.25 atm
Argon = 0.45 atm
Explanation:
According to Dalton's law of partial pressure, the total pressure in the container is equal to sum of the partial pressures of the individual gases.
Given;
Total pressure of the gases, P_total = 1 atm
Pressure of nitrogen, P_nitrogen = 0.3 atm
Pressure of oxygen, P_oxygen = 0.25 atm
Pressure of argon, P_argon = ?
Therefore, the contribution of each gas to the total pressure of the gas mixture is;
Nitrogen = 0.3 atm
Oxygen = 0.25 atm
Argon = 0.45 atm
