Answer:
27.99 dm³
Explanation:
Applying
PV = nRT................ Equation 1
Where P = Pressure, V = Volume, n = number of mole, R = molar gas constant, T = Temperature.
From the question, we were aksed to find V.
Therefore we make V the subject of the equation
V = nRT/P................ Equation 2
Given: n = 1.31 moles, T = 37°C = 310K, P = 904 mmHg = (904×0.001316) = 1.1897 atm
Constant: R = 0.082 atm.dm³/K.mol
Substitute these values into equation 2
V = (1.31×310×0.082)/(1.1897)
V = 27.99 dm³
Answer:
option d= -440 kj
Explanation:
chemical equation:
CH4 + 4Cl2 → CCl4 + 4HCl
Given data:
Bond broken energies:
C-H = 413 Kj/mol
Cl-Cl =243 Kj/mol
Bond formation energies:
C-Cl = 339 Kj/mol
H-Cl = 427 Kj/mol
Formula:
δh° = ∑n (bonds broken) - ∑m (bonds formation)
Solution:
Total bonds broken energy:
C-H = 413 Kj/mol 4×413 Kj/mol = 1652 Kj/mol
Cl-Cl = 243 Kj/mol 4×243 Kj/mol = 272Kj/mol
total = 2624 Kj/mol
Total bond formation energy:
C-Cl = 339 Kj/mol 4×339 Kj/mol = 1356 Kj/mol
H-Cl = 427 Kj/mol 4×427 Kj/mol = 1708 Kj/mol
total = 3064 Kj/mol
Now we will put the values in formula to calculate the δh° for reaction.
δh° = ∑n (bonds broken) - ∑m (bonds formation)
δh° = (2624) - (3064)
δh° = -440 kj
