Dalton’s atomic theory successfully explained- Law of conservation of mass
- Law of constant composition
- Law of radioactivity
- Law of multiple proportion
(a) (i), (ii) and (iii)
(b) (i), (iii) and (iv)
(c) (ii), (iii) and (iv)
(d) (i), (ii) and (iv)
Correct Answer: (d) (i), (ii) and (iv)
Explanation: Dalton's atomic theory proposed that all matter was composed of atoms, indivisible and indestructible building blocks. While all atoms of an element were identical, different elements had atoms of different sizes and masses.
Hence, Dalton's atomic theory explains the following laws:
- Law of conservation of mass
- Law of constant composition
- Law of multiple proportions
