13) No, I am not agree with the builder to select a marble flooring and marble top for kitchen where vinegar and juices of lemon, tamarind etc, are often used for cooking because because marble is calcium carbonate it will react with vinegar, juices of lemon, tamarind which are acid and can corrode the marble.
14) You have to draw the pH scale, it is given above question
15) POP- CaSO4.1/2H2O
Washing soda- Na2CO3.10H20
Gypsum- CaSO4.2H2O
16) CaCO3+HCl=CaCl2+CO2+H2O
