Here's the equation you use: Density = mass/volume
1) 5.2g/cm^3 = m/3.7cm^3
2) m = 5.2g/cm^3 x 3.7cm^3
3) m = 19.24g
You can check the answer by plugging it in
19.24g/3.7cm^3
= 5.2g/cm^3
Answer:
Explanation:
is insufficient to overcome intermolecular forces.
Answer:
The frequency of the photon that can dissociate dichlorine is 6.02×10¹⁴ Hz
Explanation:
The energy of a photon is given by the equation:
E=h·f
E=3.99×10⁻¹⁹ J/molecule
h (Planck's constant)=6.626×10⁻³⁴ m²·kg/s
∴ f=E/h
=6.02×10¹⁴ s⁻¹= 6.02×10¹⁴ Hz
Answer:
The kinetic energy is increasing, and the potential energy is decreasing.
