Question

9. Hydrogen and oxygen combine in the ratio of 1: 8 by mass to form H,O. What mass of onger
required to react completely with 3 gram of hydrogen gas?
10. Which postulate of Dalton's atomie
​

Answer 1

9) We know that,  1 g of hydrogen reacts with oxygen = 8 g

Therefore,  3 g of hydrogen reacts with oxygen = 8 x 3 = 24 g

Thus, 24 g of oxygen gas would be required to react completely with 3 g of hydrogen gas

10)According to the law of conservation of mass, mass can neither be created nor destroyed in a chemical reaction.
