Question

1.008 grams of hydrogen combines with 35.453 g of chlorine to form 36.463 g of a pure compound (hydrogen chloride). Dalton's explanation for this experimental fact might be:

• A. One atom of hydrogen combines with 35.453 atoms of chlorine in this reaction
• B. Hydrogen and chlorine atoms always combine in a 1:35 ratio.
• C. Chlorine accepts hydrogen's electron to form polar covalent hydrogen chloride
• D. Hydrogen and chlorine atoms aren't created or destroyed in the process so the reactant mass is the same as the product mass.

Answer 1

Answer: (D)

Hydrogen and chlorine atoms aren't created or destroyed in the process so the reactant mass is the same as the product mass.

Dalton Atomic theory postulates-

All matter is made up of atoms and atoms are indestructible cannot be created or destroyed so the total mass of reactants remains equal to the total mass of products.
