When 3 g of hydrogen combines with 14 g of nitrogen it gives off 17 g of Ammonia, how much ammonia will be formed when 3 g of Hydrogen will combine with 28 g of nitrogen ?

34 g

17 g

20 g

40 g

Ayush wanted to verify the law of conservation of mass, he burnt a piece of wood weighing 250 g in air and then he measured the mass of ashes. What will he observe ?

Mass of ashes = 250 g

Mass of ashes > 250g

Mass of ashes < 250 g

Information insufficient

Aadi thought that Why only Ayush ! So he also performed one experiment to verify the law of definite proportion, he took two samles of water one from tap water and another one from R.O. He Found the ratio of oxygen and hydrogen within the molecules of hydrogen, what will he find

Both sampes are haiving H:O = 1:8

Tap water has H:O = 1:8

R. O. Water has H:O = 1:16
