Explanation:
Hoped this helped you <\3
1) 2C₆H₆ + 15O₂ = 6H₂O + 12CO₂
2) n(C₆H₆)/2=n(CO₂)/12
n(CO₂)=6n(C₆H₆)
n(CO₂)=6*12.8 mol = 76.8 mol
Answer:
the molecules of each substance attract each other through dispersion (London) intermolecular force.whether a substance is solid, liquid or gas depends on the balance between the kinetic energies of the molecules and their intermolecular attractions.
thank you.
The frequency of a 4,600 cm wave is 652 Hz
Frequency is the number of waves that pass a fixed point in unit time
Here given data is
Wave = 4,600 cm = 4.6 × 10⁸ nm
We have to calculated frequency = ?
Frequency =v = c/λ
Frequency = 3×10⁸m / 4.6 × 10⁸ nm
Frequency = 652 Hz
