Question

When sulfur trioxide gas reacts with water, a solution of sulfuric acid forms.Express your answer as a balanced chemical equation. Identify all of the phases in your answer.

Answer 1

Answer: $SO_3(g)+H_2O(l)\rightarrow H_2SO_4(aq)$

Explanation:

According to the law of conservation of mass, mass can neither be created nor be destroyed. Thus the mass of products has to be equal to the mass of reactants. The number of atoms of each element has to be same on reactant and product side. Thus chemical equations are balanced.

The phases are represented as (s) for solid sate, (l) for liquid state, (g) for gaseous state and (aq) for aqueous state.

Thus the balanced chemical equation for :sulfur trioxide gas reacts with water, a solution of sulfuric acid forms is :

$SO_3(g)+H_2O(l)\rightarrow H_2SO_4(aq)$
