What are the different applications of electrolysis?
1. electroplating 2. extraction of metals from ores 3. electrolytic refining 4.electrolysis can also be used for coating artificial jewelery with gold to give it an attractive look . 5.electrolysis can also be used for coating cutlery made up of cheap metal with silver to give it an attractive look .
Which group in the periodic table contain only metal?
There are many groups in the periodic table that only contain metals. There are the Alkali metals, the Alkaline earth metals, Lanthanoids, Actinoids, Transition metals, and the Post-transition metals.
What are refer as group 2 metals?
they would be refered to alkaline earth metals, im only in 5th and i know.
Aluminium oxide can be separated by electricity?
there are two ways of extracting aluminum from its ore 1) old way: - displacement reaction ex: - Na + Al2O3 ==> Na2O + Al 2) new way: electrolysis electrolysis: - is a way of extracting highly reactive metals from their ore using electricity. so the short answer is YES
What is the ratio of gases evolve on electrolysis of water?
The ratio of gases evolved during the electrolysis of water is 2:1 for hydrogen gas to oxygen gas. This means that for every 2 molecules of hydrogen gas produced, 1 molecule of oxygen gas is produced.

Why is barium the most difficult group 2 metal to extract by eletrolysis?
Barium is the most difficult Group 2 metal to extract by electrolysis because it has the lowest electrode potential among the Group 2 metals, making it harder to form barium ions at the cathode. This results in a higher energy requirement for the electrolysis process compared to other Group 2 metals, making it less efficient and more challenging to extract barium.

In what compuonds is oxygen found and how is it extracted?
Oxygen can be found in H20 (water). It can be separated through electrolysis The equation for the electrolysis of water is 2[H20]+energy = 2[H2] + 02
What is the electrolysis of sodium chloride?
1. The products of the molten sodium chloride electrolysis are sodium and chlorine. 2. The products of the water solution of sodium chloride electrolysis are sodium hydroxide and hydrogen.
Which metals are not metals?
4 metals are not magnetic 1. Aluminium 2. Gold 3. Copper 4. Brass these metals can only be magnetised by very scientific work which i cannot understand 5. don't forget silver...
In the periodic table what group contains only metals?
All the element in group 1 are metals except for hydrogen which if you notice, is not exactly in group 1. It is situated away from the periodic table because it can react as a metal as well as a non metal. Hope this helped...
What are the products when water is broken down by electrolysis?
The two products when water is broken down by electrolysis is hydrogen gas and oxygen gas. The energy source in photosynthesis is light energy.

Do all alkaline metals have 2 electron shells?
No. All the alkaline earth metals have 2 valence electrons, meaning they have two electrons in the outermost shells. No two alkaline earth metals have the same number of electron shells. Beryllium is the only one with two shells.
What is the most active family the metals?
Group 1 is the most active and Group 2 is second.
