Na2O + HCl - > NaCl + H2O

Does this equation satisfy the Law of Conservation of Matter? Why or why not?

A) Yes, since there are 5 reactant atoms and 5 product atoms.

Eliminate

B) Yes, since there is a subscript of 2 on both sides on the equation.

C) No, since there are two sodium atoms as reactants, but only one sodium atom as a product.

D) No, since there is a liquid and a solid as reactants, but a gas and a solid as a product

Na2O + HCl→ NaCl + H2O

Does the equation above satisfy the law of mass conservation of matter.

No, since there are two sodium atoms as reactants, but only one sodium atom as a product.

Explanation

According to the law of mass conservation the number of atoms in the reactant side must be equal to the number of atoms in the product side.

For this reason the equation above does not satisfy the law of mass conservation since the number of sodium atoms are not equal in both side.
