Electricity can bring about chemical changes, so it is said to have chemical effects. The breaking up of water into hydrogen and oxygen is actually a' chemical decomposition' reaction caused by passing an electric current through impure water.
Michael Faraday, a well- known British experimental physicist, began his experiments on the passage of electricity through liquids (electrolyte) in 1834. He observed interesting chemical changes (effects) taking place when an electric current pass through an ionic solution.
Which of the following are correct : (a) Michael Faraday, a well- known British experimental physicist, began his experiments on the passage of electricity through liquids (electrolyte) in 1834. (b) Issac Newton, a well- known British experimental physicist, began his experiments on the passage of electricity through liquids (electrolyte) in 1834. (c) When electric current is passed through acidified water by using carbon electrodes, than a chemical reaction takes place to form hydrogen gas and oxygen gas. | |||

Being a parent, I saw my daughter improvement in her studies by seeing a good result in all day to day compititive exam TMO, NSO, IEO etc and as well as studies. I have got a fruitful result from my daughter.
A marvelous experience with Abhyas. I am glad to share that my ward has achieved more than enough at the Ambala ABHYAS centre. Years have passed on and more and more he has gained. May the centre flourish and develop day by day by the grace of God.
About Abhyas metholodology the teachers are very nice and hardworking toward students.The Centre Head Mrs Anu Sethi is also a brilliant teacher.Abhyas has taught me how to overcome problems and has always taken my doubts and suppoeted me.
It has a great methodology. Students here can get analysis to their test quickly.We can learn easily through PPTs and the testing methods are good. We know that where we have to practice
It was a good experience with Abhyas Academy. I even faced problems in starting but slowly and steadily overcomed. Especially reasoning classes helped me a lot.
It was good as the experience because as we had come here we had been improved in a such envirnment created here.Extra is taught which is beneficial for future.
My experience with Abhyas is very good. I have learnt many things here like vedic maths and reasoning also. Teachers here first take our doubts and then there are assignments to verify our weak points.
My experience with Abhyas academy is very good. I did not think that my every subject coming here will be so strong. The main thing is that the online tests had made me learn here more things.
I have spent a wonderful time in Abhyas academy. It has made my reasoning more apt, English more stronger and Maths an interesting subject for me. It has given me a habbit of self studying
My experience was very good with Abhyas academy. I am studying here from 6th class and I am satisfied by its results in my life. I improved a lot here ahead of school syllabus.
