Show Solution
Verified By Collegedunia
The Correct Option is B
Solution and Explanation
Step 1: Recall the function of Hopcalite.
Hopcalite is a catalyst composed mainly of manganese dioxide and copper oxide.
Step 2: State its application. It converts toxic carbon monoxide into carbon dioxide and is therefore used in \[ \boxed{\text{Gas masks}.} \] Hence, \[ \boxed{(B)} \] is the correct answer.
Step 2: State its application. It converts toxic carbon monoxide into carbon dioxide and is therefore used in \[ \boxed{\text{Gas masks}.} \] Hence, \[ \boxed{(B)} \] is the correct answer.
