Question

Is the following equation balanced?
SO 3 + 2H 2 O H 2 SO 4
yes or no

Answer 1

No , This equation is not -balanced :

The correct balanced equation is

`SO_(3) + H_(2)O\rightarrow H_(2)SO_(4)`

Step-by-step explanation:

Law Of conservation of Mass = It states that mass can neither be created nor destroyed, however it can be transferred from one substance to other.

or

Total number of atoms remain constant :

Total number of atoms present in the reactant = Total number of atoms present in the reactant .

In the given equation H and O are not- balanced. There are 4 H inn reactant and only 2 in product. O is also unbalanced . 5 oxygen in reactants and only 4 in product

Consider :

`SO_(3) + H_(2)O\rightarrow H_(2)SO_(4)`

Reactant :

`SO_(3) + H_(2)O`

Number of S = 1

Number of O = 3 (from SO3) + 1 (from H2O)= 4

Number of H = 2

Product :

`H_(2)SO_(4)`

Number of S = 1

Number of O = 4

Number of H = 2

`SO_(3) + H_(2)O\rightarrow H_(2)SO_(4)`

It is balanced because

Number of atoms in reactant = product
