Question

Pbcl2 pb + cl2 does the chemical reaction shown above obey the law of conservation of mass?

Answer 1

Answer : Yes, the given chemical reaction obey the law of conservation of mass.

Explanation :

Law of conservation of mass : It states that mass can neither be created nor be destroyed but it can only be transformed from one form to another form.

The balanced chemical reaction always follow the law of conservation of mass.

Balanced chemical reaction : It is defined as the reaction in which the number of atoms of individual elements present on reactant side must be equal to the product side.

The given chemical reaction is,

$PbCl_2\rightarrow Pb+Cl_2$

This reaction is a balanced chemical reaction in which number of atoms of lead and chlorine are equal on the both side of the reaction. So, this reaction obey the law of conservation of mass.

Hence, the given chemical reaction obey the law of conservation of mass.

Answer 2

Yes because the equation is balanced!
