2H₂ + O₂ ⇒ 2H₂O
<h3>Further explanation</h3>
Conservation of mass states that
<em>In a closed system, the masses before and after the reaction are the same</em>
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

C₈H₁₈ is a non-electrolyte
Why?
Electrolytes are substances that dissociate into ions when dissolved in water. In order to do that, they need to have bonds that are polar enough to be able to dissociate, and the ions formed need to be soluble in water.
C₈H₁₈ is a compound that has a low electronegativity difference between its atoms, making it to be a covalent compound where electrons are shared, and making it non-polar, and difficult to dissociate. Thus, it is a non-electrolyte.
One possible structure for C₈H₁₈ is attached below. It's called octane.
Have a nice day!
