Solution

The correct option is B Law of conservation of mass
In the given reaction,
$Sodium carbonate (14 g) + Ethanoic acid (10 g) \Rightarrow (S o d i u m e t h a n o a t e + w a t e r) (16.67) + C a r b o n d i o x i d e g a s (7.33 g)$
Total mass of all reactants combined
$= 14 g + 10 g = 24 g$
Total mass of all the products formed
$= 16.67 g + 7.33 g = 24 g$ .
It is observed that Total mass of all reactants combined $= 24 g =$ Total mass of all the products formed. Therefore, the given observations are in agreement with the law of conservation of mass.
