Answer:
The reaction is spontaneous.
Explanation:
If voltaic cell show positive charge it means reaction is spontaneous taking by itself.
Answer:
Bohr used emission spectrum for its mono atomic model....
Explanation:
Emission Spectrum is produced when atoms are excited by energy. After excitation, they emit this energy in the form of different wavelengths according to the type of atom and produce a unique fingerprint of themselves called as it's emission spectrum.
Absorption Spectrum is a type of spectrum that is produces when photons of light are absorbed by electrons at one state. they jump to another state and may cause scattering. This produces a specific absorption spectrum for that specific atom.
<span>Oxygen obey the octet rule when reacting to form compounds by adding 2 electrons. Its means the charge on Oxygen is -2.
</span>It has oxidation state −1 is found in a few compounds such as <span>peroxides.</span>
