Question

Dalton based his theory on the -

• A. Law of conservation of mass
• B. Law of constant composition
• C. Both options $\left(A\right)$ and $\left(B\right)$
• D. None of these

Answer 1

The correct option is C Both options $\left(A\right)$ and $\left(B\right)$

Dalton's theory says -

$\left(i\right)$ Atoms can neither be created nor be destroyed - Law of conservation of mass

$\left(ii\right)$ Compounds are combinations of two or more different types of atoms in the same proportion - Law of constant composition

Hence, option $\left(C\right)$ is the correct answer.
