Question

The reaction of formation hydrogen chloride form hydrogen and chlorine represents which chemical reaction

Answer 1

It's a combination reaction and also a redox reaction where Hydrogen's oxidation State increases from 0 to +1 while that of chlorine decreases from 0 to -1.

Answer 2

Here the combination reaction takes place.

Here ,

Hydrogen + Chlorine → Hydrogen Chloride

We can write it in the equation form and a balanced equation too.
