Question

Prove that 2H₂ + O₂ → 2H₂O obeys Law of conservation of mass.

Answer 1

Answer:

law of conservation of mass states that the total enrgy before and after the reaction remains same.that is the energy in the reactant side=energy in the product side.

Explanation:

no.of moles of h2 is 2 and no of moles of oxygen is 8*2=16

now total no of moles in reactant side=2+16=18

in the product side 2h20,

2*1+2*8=18

no of moles in reactant side = no of moles in product side.

so it obeys la of conservation of mass.
