Pbcl2 pb + cl2 does the chemical reaction shown above obey the law of conservation of mass?
2 answers:
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,
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:
1) 0.18106 M is the molarity of the resulting solution.
2) 0.823 Molar is the molarity of the solution.
Explanation:
1) Volume of stock solution =
Concentration of stock solution =
Volume of stock solution after dilution =
Concentration of stock solution after dilution =
( dilution )
0.18106 M is the molarity of the resulting solution.
2)
Molarity of the solution is the moles of compound in 1 Liter solutions.
Mass of potassium permanganate = 13.0 g
Molar mass of potassium permangante = 158 g/mol
Volume of the solution = 100.00 mL = 0.100 L ( 1 mL=0.001 L)
0.823 Molar is the molarity of the solution.
