Answer: There are various indicators like litmus paper, phenolphthalein, universal indicator etc. that changes its colour to show the difference between acid and alkali.
2 mol of H2S react with 3 mol of O2
5.6 mol of H2S react with =5.6×3/2=8.4 mol of O2
Answer:
1=100 1 Kilogram (kg) is equal to 100 dekagrams (dag). To convert kilograms to dekagrams, multiply the kilogram value by 100.
Explanation:
Answer:
The study of the interaction of electrical and magnetic fields, and their interaction with matter, is called Electromagnetism
Mole of electron required by
mole is 
- Faraday law expressed how the change that is been being produced by a current at an electrode-electrolyte interface is related and proportional to the quantity of electricity that is been used.
- There is one mole of electron required for 1 Faraday of electricity.
- Avogadro constant is

- Mole of electron can be calculated by dividing the number of electron by avogadro's constant.
=
= 
Therefore, it requires
Faraday of electricity for the
