 The Law of Conservation of Mass is best represented by which chemical equation below:

EXPLAIN WHY!

a.)  CH4 + 3O2 ===> CO2 + 2H2O

b.)  Al4C3 + 3H2O ===> CH4 + 4Al(OH)3

c.)  2H2O ===> H2 + O2

d.)  Zn + 2HCl ===> ZnCl2 + H2

What is choice d.) because it is balanced - no matter was created or destroyed!
