When a glowing splint bursts into flames during the decomposition of h2o2, it indicates that which gas is produced?

The correct answer is oxygen.

Explanation:

The glowing splint bursts into flames during the decomposition of hydrogen peroxide, which shows that the production of oxygen is taking place, as the presence of oxygen enhances the combustion reaction of the splint substance. The more the concentration of oxygen, the more will be the glowing splint bursting into flames.  

The glowing splint test refers to a basic qualitative test, which is generally used to assess oxidizing gases.  

in chemistry, adhesion and cohesion are attractive forces that exist between molecules. they hold the molecules together from each other. they are different in that adhesive force exists between molecules of different substance while cohesive force happens between molecules of same substance.

adhesion between water and glass causes water molecules at the edge of water and glass interface to climb up the wall in a narrow glass tube. this is called capillary action. cohesion is what gives glass its shape and causes water to form a droplet.
