Answer:

Chemical reaction.

Step-by-step explanation:

In the experiment, a catalyst is added to concentrated hydrogen peroxide.

The hydrogen peroxide <em>decomposes</em> rapidly, according to the equation

2H₂O₂(ℓ) ⟶ 2H₂O(ℓ) + O₂(g)

New substances are formed, and old ones disappear, so this is a chemical reaction.

The reaction also releases a <em>large amount of heat</em>.

The rapidly-expanding oxygen gas caries with it droplets of water and hydrogen peroxide (and probably some steam, as well).

The visual effect is like a genie escaping from its bottl<em>e</em>.

Which compound reacts with a base in the bicarbonate buffer system in the human body? Carbon dioxide carbonic acid bicarbonate i

denis23 [38]

Bicarbonate buffer system in blood consists of carbonic acid and bicarbonate ion. H2CO3/HCO3-

When a base enters the body the acid part of the buffer reacts with the base.

Thats the carbonic acid (H2CO3) reacts with the base.
