Answer:
C. 2H₂ + O₂ ⇒ 2H₂O
Further explanation
Conservation of mass states that in a closed system, the masses before and after the reaction are the same. So it can be concluded
mass of the reactants = mass of the products
mass cannot be created or destroyed
The number of atoms involved in a reaction remains the same⇒ number of moles also the same
chemical equation in balanced form
So let's see which of the several options , which one has the same number of atoms on both sides of the equation
2H₂ + O₂ ⇒ 2H₂O
H ⇒ left 4, right 4
O ⇒ left 2, right 2
so the equation is in balance and represents the Law of Conservation of Mass
