Answer: The correct answer is in chemical bonds
Explanation:
When coal is burnt, these components burn and release energy. The energy released is by the chemical reaction between the constituents and oxygen
Compound is a pure substance where atoms of two or more elements are chemically bonded togather
Answer:
The energy difference between these 2p and 2s orbitals is
Explanation:
Wavelength of the photon emitted =
Energy of the photon will corresponds to the energy difference between 2p and 2s orbital = E
Energy of the photon is given by Planck's equation:
h = Planck's constant =
c = Speed of the light =
The energy difference between these 2p and 2s orbitals is
