Answer 1

Cl₂ 

Explanation:

Cl₂ (Chlorine) is a bleaching chemical used to turn wood pulp into white paper. 
A bleaching agent is a chemical that has the ability to whiten or decolorize other materials. The amount of organochloride chemical produced is reduced when chlorine dioxide is used. 
Chlorine dioxide is used in ECF bleaching 
sequences to make around 95% of all bleached Kraft pulp.
