Answer 1

1) Chlorine is made commercially form electrolisis of molten common salt (sodium chloride) according to the following chemical reaction:

2 NaCl + 2 H2O → Cl2 + H2 + 2 NaOH

2) Litmus paper will turn red, becasue chlorine will dissociates in the little amount of water that litmus paper has yielding HCl (hydrocloric acid that is the auqueos form of the Hydrogen chloride)

3) It produces Hydrogen chloride (HCl).

C2 + H2 -------> 2HCl

Hope it helps!

Answer 2

1) Chlorine is commercially made by the electrolysis of molten sodium chloride.

2) Wet blue litmus will initial turn the paper red (as chlorine is acidic) then white (as it is a bleach).

3) Hydrogen will react with chlorine to produce hydrogen chloride according to

H2 (g) + Cl2 (g) -------------> 2HCl (g)

Answer 3

2. chlorine gas turns moist blue litmus red first and then bleach the paper.

3. H2 + Cl2 -> 2HCl

if i'm rite. haas.
