LiRa [457]
Hydrogen sulfide = hidrogen + sulfur

       6.500 g                      

a)                             0.384 g   +    x

=> 6.500 = 0.384 + x => x = 6.500 - 0.384 = 6.116 g

Answer: 6.116 g of sulfur must be obtained

b) this experiment demonstrate the conservation of mass.

c) Dalton's atomic model states that the atoms cannot be created, split or be destroyed, and so in a chemical reaction the atoms rearrange but the number of each type of atoms remain constant, so the mass of each type of atoms and the total mass remain constant.
