Vedclass · Accepted Answer

Statement $1$ and Statement $2$ are both true,and Statement $2$ is the correct explanation of Statement $1$.

Vedclass · Answer

(A) Statement $1$ is true because water $(H_2O)$ always contains hydrogen and oxygen in a fixed mass ratio of $2:16$,which simplifies to $1:8$,regardless of the source.Statement $2$ is true because Joseph Proust formulated the Law of Definite Proportions in $1799$,which states that a chemical compound always contains exactly the same proportion of elements by mass.Since Statement $1$ is a direct application of the Law of Definite Proportions (Statement $2$),Statement $2$ is the correct explanation for Statement $1$.

Compound	$\% Sn$	$\% O$
$A$	$78.77$	$21.23$
$B$	$88.12$	$11.88$

Statement $1$: The mass ratio of hydrogen to oxygen in water obtained from rivers,wells,lakes,or seas is always $1:8$.
Statement $2$: In $1799$,the scientist Joseph Proust proposed the Law of Definite Proportions.
