Question

19. Phosphorus forms two chlorides. A 30.0g sample of one chloride decomposes to give 4.35g of P and 25.65g of Cl. A 30.00g sample of the other chloride decomposes to give 6.61g of P and 23.39g of Cl. Show that these compounds obey the law of multiple proportions.

20. Nitrogen monoxide, NO, is produced in internal combustion engines. When NO comes in contact with air, it is quickly converted to NO₂, nitrogen dioxide, a very poisonous corrosive gas. What mass of O is combined with 1.00g of N in: NO, NO₂. Show that NO and NO₂ obey the Law of Multiple Proportions.
