Vedclass · Answer

(C) Dalton's atomic theory was proposed to explain the fundamental laws of chemical combination.$(i)$ Law of conservation of mass: Dalton's theory states that atoms can neither be created nor destroyed in a chemical reaction,which explains this law.$(ii)$ Law of constant composition (or definite proportions): The theory states that the relative number and kinds of atoms are constant in a given compound,which explains this law.$(iii)$ Law of radioactivity: This law relates to nuclear physics and the instability of atomic nuclei,which was not part of Dalton's atomic theory.$(iv)$ Law of multiple proportion: Dalton's theory explains this law by stating that atoms combine in simple whole-number ratios to form compounds.Therefore,Dalton's theory successfully explained $(i), (ii),$ and $(iv)$.

Dalton's atomic theory successfully explained which of the following laws?
$(i)$ Law of conservation of mass
$(ii)$ Law of constant composition
$(iii)$ Law of radioactivity
$(iv)$ Law of multiple proportion
