The internal energy of a substance Is called​

Chemistry
1 answer:
Gennadij [26K]3 years ago
4 0

Answer:

The internal energy is the total amount of kinetic energy and potential energy of all the particles in the system. ... When the substance melts or boils, energy is put in to breaking the bonds that are holding particles together, which increases the potential energy.

For the reaction 6 Li + N2 → 2 Li3N , what is the maximum amount of Li3N (34.8297 g/mol) which could be formed from 14.18 mol (6
Yuki888 [10]
Moles Li = 3.50 g / 6.941 g/mol= 0.504
the ratio between Li and N2 is 6 : 1
moles N2 required = 0.504 /6=0.0840
we have 3.50 g / 28.0134 g/mol=0.125 moles of N2 so N2 is in excess
the ratio between Li and Li3N is 6 : 2
moles Li3N = 0.504 x 2 /6=0.168
mass Li3N = 0.168 mol x 34.8297 g/mol=5.85 g

One of the postulates of bohr's atomic model of a moving electron is that angular momentum of a moving electron is quantized. Ex
oksano4ka [1.4K]

The angular momentum of an electron in the third Bohr orbit of a hydrogen atom is given by mvr=3h÷2π

<h3>What is momentum?</h3>

Momentum is defined as the amount of motion occurring in something that is moving, or the force that drives something forward to keep it moving.

Bohr never assumed stable electronic orbits with the electronic angular momentum quantized as

l=mvr = \frac{nh}{2pi}

Quantization of angular momentum means that the radius of the orbit and the energy will be quantized as well.

Bohr assumed that the discrete lines seen in the spectrum of the hydrogen atom were due to transitions of an electron from one allowed orbit/energy to another.
