Answer:
0.0253 M/s
Explanation:
From the reaction
N₂ + 3H₂ → 2NH₃
The rate of reaction can be written as
Rate = - = - = +
From the above rate equation we can conclude that the rate of reaction of N₂ is equal to one third of the rate of reaction of H₂,
So,
Rate of reaction of molecular nitrogen =
Upon calculation, we get rate of reaction of molecular nitrogen = 0.0253 M/s
On top of a clear liquid, a black powder is put. The test tube starts to fizz and bubble, and it also gets hot to the touch. A gas is formed, and then there is a color change from the light and heat it emission.
Light may be absorbed and emitted by atoms and molecules, which allows us to determine the number of energy levels an electron has as well as the distance between those levels. The photon energies that correspond to various colors of light vary. In essence, a photon is a bundle of light. A photon of red light would have less energy than a photon of blue light, for instance. Red and blue have different wavelengths, and since red has a longer wavelength than blue, it has a lower energy. Only in shells, which surround nuclei, do electrons actually exist. Shells are matched to specific energy levels. The process of emission is the release of various colour photons by elements as their atoms decelerate to lower energies. When heated or stimulated, atoms release light.

1.) A compound is a substance that originates from two or more separate elements. It shares some similarities with a mixture.
2.) A compound has quite different properties from which it was formed. It also cannot be separated easily. Compounds are formed by chemical reactions.
3.) A pure substance has a constant composition and has consistent properties. It can be a compound or an element, but its composition is constant.
Hope this helps. :)
Answer:
The process of combining the smaller nuclei to make larger one is called fusion.
Fusion occurs on the sun.
Explanation:
Fusion:
It is the process in which smaller nuclei combine to form the larger nuclei.
Fusion process also occur in the sun.
It is known as proton-proton fusion. In this proton-proton fusion, the atoms of hydrogen fused together and form helium-4. This is accomplished through several steps hydrogen atoms combine to form deuterium.
This deuterium atom fused with proton and form helium- 3.
Gamma rays are also produced in this reaction.
This helium-3 combine with another helium-3 and form helium-4 atom and two protons.
