Answer:

Answer:  The wrong part is that the Hydrogen and Oxygen in this reaction never appear as a single atom , it is always in a gas molecule form which is H2 and O2  

Explanation:

 

Explanation:

Given equation -> H+O->H2O

Correct or Balanced Equation -> H2+O2->H2O

Simple, H + O = H2O is not balanced. This is why it's wrong.

We have a law in chemical combinations called Law Of Conservation Of Mass. This law states that, in a chemical equation, total mass of the reactants will ALWAYS be equal to the total mass of the products.

==> H + O = H2O

Let's look at the mass of the reactants, H + O

= 1g + 16g = 17g

(∵Atomic mass of hydrogen is 1g, and oxygen is 16g)

Now, mass of the products, H2O

= (1×2) + 16 = 18g

So, here the equation is WRONG because mass of reactants ≠ mass of products.

This is why we balance this equation, I.e, to follow this principle.

Now, the balanced form of the equation will be:-

2H2 + O2 → 2H2O

Mass of reactants, 2H2 + O2

= 2(1 × 2) + (16×2) = 36g

Mass of products, 2H20

= 2(1×2 + 16) = 36g

Now, this is correct because both sides of the equation is balanced, I.e, Atomic mass of reactants will be equal to that of products.
