The total energy includes sensible heat to raise the temperature from 75.1°C to the boiling point. It also includes the latent heat to convert the liquid to gas. Then, it also includes sensible heat from he boiling point to 115.1°C. The equation is:
Energy = nCp,liquid(T,bp - T₁) + nΔH + nCp,gas(T₂ - T,bp)
where
n is the number of moles
T,bp is the boiling point of benzene at 80.1°C
Cp,liquid = 134.8 J/mol·°C
Cp,gas = 82.44 J/mol·°C
ΔH = 87.1 J/mol
Energy = (3.12 moles)(134.8 J/mol·°C)(80.1°C - 75.1°C) + (3.12 moles)(87.1 J/mol) + (3.12 moles)(82.44 J/mol·°C)(115.1°C - 80.1°C)
Energy = 11,377.08 J
It avoids confusion through scientists. If you think, they could be practicing or studying in varying countries and something uniform for science avoids all confusion!
Answer:
evaporates
Explanation:
the heat from the sun causes it to evaporate
Answer:
[N2] = [O2] = 0.841M
And [NO] = 0.00172M
Explanation:
The equilibrium constant of this reaction, Kc, is:
Kc = 2400 = [N2] [O2] / [NO]²
<em>Where [] are the equilibrium concentration of each specie.</em>
<em />
The initial concentration of [N2] = [O2] = 0.850M. The equilibrium will shift to the left in order to produce NO. The equilibrium concentrations are:
[N2] = [O2] = 0.850M - X
And [NO] = 2X
Replacing:
2400 = [0.850-X]² / [2X]²
9600X² = 0.7225 - 1.7 X + X²
0 = 0.7225 - 1.7 X - 9599X²
Solving for X:
X = -0.0088M. False solution, there is no negative concentrations.
X = 0.00859M. Right solution.
Replacing:
[N2] = [O2] = 0.850M - 0.00859M
And [NO] = 2*0.00859M
[N2] = [O2] = 0.841M
And [NO] = 0.00172M
Answer:
it will change
