If the acid is 100 percent dissociated in solutions of 1.0 M or less, it is called strong. Sulfuric acid is considered strong only in its first dissociation step; 100 percent dissociation isn't true as solutions become more concentrated.
Answer:
Principle quantum number.
Explanation:
Explanation:
The given data is as follows.
n = 1 mol, 
Q = 1500 J, R = 8.314 J/mol k
(a) 
And, according to the first law of thermodynamics

And, in an isothermal process the change in internal energy of the gas is zero.
Hence, 0 = Q - W
or, W = Q
Expression for work done in an isothermal process is as follows.
W = 
As W = Q, Hence expression for Q will also be given as follows.
Q = 
Now,

[/tex]\Delta S = nR ln \frac{V_{f}}{V_{i}}[/tex]
= 
= nR ln 2
= 
= 5.76 J/K
Therefore, change in entropy is 5.76 J/K.
(b) As, Q = 
= 
= nRT ln 2
T = 
= 
= 260.4 K
Therefore, temperature of the gas is 260.4 K.

trust me bro ive done this
Answer:
One mole of CO2 has mass of 44 g and 32 g of O2. So 16 g of O2 have 22 g of CO2 or 0.5 moles of it.
