Question

Does the equation N2+H2 →NH3 follow the Law of Conservation of Mass?

  1. Yes, because atoms on both sides are equal.
  2. No, there are more info is needed.
  3. No, because there are more atoms in reactant side
  4. Yes, because the minimum condition is fulfilled.

hintHint:

mass of reactants = mass of products.

The correct answer is: No, because there are more atoms in reactant side


    • The law of conservation of mass states that mass can neither be created nor destroyed. It can be also stated as the mass of the reactants is equal to the mass of the products.
    • We can see that there are two nitrogen and two hydrogens on the reactants side and one nitrogen and three hydrogens on the products side. This means the reaction does not follow the law of conservation of mass.

    While verifying the law of conversation of mass, Ron added 4.5 g of magnesium metal to 15.5 g of hydrochloric acid. If mass of the magnesium chloride formed is 16.9, what is the mass of eliminated hydrogen gas if the law of conservation of mass is valid for this change.
    Mg +  2HCl →  MgCl2 +  H2
