When hydrogen (h2) and chlorine (cl2) gases are mixed, hydrogen chloride (hcl) is produced. hydrogen chloride is classified as what type of matter?

Gaseous matter

Explanation:

Hydrogen chloride gas is formed from the combination of volumes of hydrogen gas and chlorine gas in equal proportion. It is one of the hydrogen halides I.e a compound formed from the combination of hydrogen and halogens.

Hydrogen chloride gas is a colorless gas.

Both hydrogen gas and chlorine gas can be obtained through the electrolysis of brine in the chlor alkali process.

Cl2(g) + H2(g) → 2 HCl(g)

The combination is exothermic and thus heat is released to the surroundings. A construction called HCl burner is used to carry out the reaction because of the heat given off. The produced gas is then absorbed in water
