Question

Hydrogen + Chlorine -> Hydrogen chloride .Write the balanced chemical equation.

Answer 1

H₂(g)+Cl₂(g)------->2HCl(g)
Where,
H-Hydrogen
Cl-Chlorine
HCl-Hydrogen chloride
(g)-gaseous state

Answer 2

The balanced equation:
$H_{2} + Cl_{2}=2HCl (g)$
H is Hydrogen
Cl is chlorine
HCl is hydrochloric acid.
(g) represents that it is in its gaseous state..
There fore , to prepare liquid HCl ( which is more commonly used) , we will dissolve the HCl gas in water (which is also easily soluble).
Therefore:
$2HCl (g) = 2HCl(l).$
