Answer:- The pressure of ethanol would be 109 mmHg.
Solution:- This problem is based on Clausius clapeyron equation--
Given, = 63.5 + 273 = 336.5 K
= 34.9 + 273 = 307.9 K
= 400 mmHg
= ?
= 39.3 kJ/mol = 39300 J/mol
R = 8.314 J/mol.K
Let's plug in the values in the equation and do the calculations.
= 1.30
On taking anti ln to both sides...
=
= 3.67
= 400/3.67
= 109 mmHg
Answer: electron donor.
Explanation:
According to Arrhenius concept, a base is defined as a substance which donates hydroxide ions when dissolved in water and an acid is defined as a substance which donates hydronium ions
in water.
According to the Bronsted Lowry conjugate acid-base theory, an acid is defined as a substance which donates protons and a base is defined as a substance which accepts protons.
According to the Lewis concept, an acid is defined as a substance that accepts electron pairs and base is defined as a substance which donates electron pairs.
Here acts as lewis base and
act as lewis acid.
Thus lewis base is defined as an electron pair donor.
Answer : The temperature of gas is, 295 K
Explanation :
To calculate the temperature of gas we are using ideal gas equation:
where,
P = Pressure of gas = 1.21 atm
V = Volume of gas = 10.0 L
n = number of moles = 0.500 mole
R = Gas constant =
T = Temperature of gas = ?
Now put all the given values in above equation, we get:
Therefore, the temperature of gas is, 295 K
