Answer:
In general, a scientific law is the description of an observed phenomenon. It doesn't explain why the phenomenon exists or what causes it. The explanation of a phenomenon is called a scientific theory. It is a misconception that theories turn into laws with enough research.
Answer:
The balanced equations for the reactions are outlined below:
Explanation:
A balanced equation describes how many (number of moles) atoms of the reactant give rise to how many (number of moles) of product.
- Hydrogen sulfide gas () and oxygen gas () react to produce sulfur dioxide gas () and water vapor gas.
- The balanced equation for the reaction, taking into consideration the states is:
→
Vanadium(II) oxide (VO) is oxidized by iron(III) oxide (Fe2O3) resulting in the formation of vanadium(V) oxide (V2O5) and iron(II) oxide (FeO).
The balanced equation:
→
Answer : Nuclear fusion plays an important role in making elements that are heavier than helium.
Explanation : In the given attachment it is clearly observed that nuclear fusion reactions are playing a vital role in making the small elements fuse together to form a higher element as a product. This is observed in those elements which are heavier than helium. The atoms of the elements fuse together and make a larger atomic molecule which is the sum of both the elemental masses.
Answer:
The names of the electron shell were given by a spectroscopist named Charles G Barkla. He named the innermost shell has k shell because he noticed that the X-rays emitted two types energies. These energies were named as type A that is higher energy X-ray and type B that is lower energy X-ray. Later these energiers were named with different alphabets. He noticed that K type X-rays emitted the highest energy. Therefore, he named the innermost shell as the K shell.

<h2>#hope</h2>
The alkene will not react as potassium dichromate because it's not strong enough but it will react with acidified potassium manganate which is a stronger oxidizing agent.
