In order to determine the frequency, we may use Planck's equation:
Energy = Planck's constant * frequency
Rearranging and substituting the values,
frequency = (1.8 x 10⁻¹⁵) / (6.63 x 10⁻³⁴)
f = 2.71 x 10¹⁸ Hz
The frequency of the light is 2.7 x 10¹⁸ Hz
Answer:
102.0 g/mol.
Explanation:
Aluminum oxide or Al2O3 is a chemical compound composed of 3 Oxygen and 2 aluminum atoms. Naturally, it is present in the form of mineral corundum in crystalline polymorphic forms. It holds significant importance in the preparation of Aluminium metal that is used as a refractory material.
To calculate the molar mass of Aluminum oxide, we will add the molar mass of 2 Al and 3 O atoms.
Since molar mass of Al is: 26.98 g
Molar mass of O is: 16.00 g
Molar mass of Al2O3
= (26.98)2 + (16.00) 3
= 53.96 + 48
= 101.96 g/mol
Since it is mentioned in question to round off the answer upto 4 significant figures, it will make the answer: 102.0 g/mol.
Hope it help!
Answer:
Sorry, I'm trying to think but i cant explain..
Explanation:
Nuclear fusion produces more energy with less radioactive waste compared to nuclear fission process.
- In nuclear fission, a radioactive decay occurs in which a heavy nucleus spontaneously disintegrates into two lighter nuclei and several neutrons with the release of energy.
- Nuclear fusion occurs when small atomic nuclei combines into larger ones with the release of a large amount of energy.
- Instability of a nuclide is enough to start up a nuclear fission reaction. In some instances, a heavy nuclide is bombarded with another nuclide.
- In nuclear fusion, the activation energy required to start up is very great.
Nuclear wastes emanating from nuclear fusion process is least compared to that of nuclear fission.
Nuclear fusion produces more energy compared to nuclear fission process.
