Potential difference is the amount of work done in moving 1 coulomb of charge in a unit time.
Taj Mahal, the great wonder of the world, is made of white marble which is composed of calcium carbonate. About 60 years ago it was discovered that this monument is being eaten away by acid rain. The Archeological survey of India, that looks after this building of historical importance is of the opinion that the atmospheric pollution due to vehicular traffic and industries, mainly Mathura Refinery may be a major cause of acid rain in and around the monument. Normal rain is slightly acidic because it absorbs some CO, from the atmospheric air. Acid rain is more acidic than normal rain because it also has absorbed oxides of nitrogen and sulphur. (a) What happens when marble is heated? Write the chemical reaction. What type of reaction is it. Name the product formed in this reaction which is used in the manufacture of cement. How will you test the gas evolved in this reaction. (b) Write down observations which help us to determine whether a chemical reaction has taken place or not. Or (b) A solution of a substance "X" is used for white washing. () Name the substance X and write its formula. (i) Write the reaction of substance X with water.
