HCO3- is both an acid and a base. It can donate a "proton" (hydrogen ion) as follows:
HCO3(-) = H(+) + CO3(-2)
or
HCO3(-) + OH(-) = H2O + CO3(-2)
It can also absorb a proton:
HCO3(-) + H(+) = H2CO3
Which occurs depends on the pH of the solution. The pKa values are given here:

H2CO3 is known as "carbonic acid". It can decompose into water and carbon dioxide
H2CO3 = H2O + CO2

Is sulfuric acid a bronsted acid bronsted base or both?
It's a Brønsted Acid because it gives up a proton in water.
Is NH4 plus a bronsted acid?
The Bronsted-Lowry definition of an acid is a species which can give up an H+ ion, and HSO4- can deprotonate to give SO42- and H+. This is where the second hydrogen ion from sulfuric acid comes from.
Is H2O Bronsted acid or base or both?
Yes OH is in fact a Bronsted base making H3O a acid
Which if the following is an example of a bronsted-lowry acid?
Substances that can act both as an acid and as a base are called
Which compound can act as both a bronsted-lowry acid and a bronstey-lowry base?
Ammonia (NH3) --> can become NH2- or NH4+ Water (H2O) --> can become OH- or H3O+

Is calcium hydrogencarbonate an acid base or neutral?
Calcium ions are neutral and hydrogencarbonate ions are: (!!) BOTH acid AND base at the same time, both very weakly, though it is a bit more base than acidic:acid: HCO3- + H2O --> CO32- + H3O+ pKa=10.25base: HCO3- + H2O -->H2CO3 + OH- pKb= 7.64
Is chicken a base or acid?
A base.

Acid
Are reactants in a neutralization reaction acid or base?
both acid and base
Is anti acid a base or acid?
both
