How to balance the equation for the reaction of aluminum bicarbonate and hydrochloric acid? Here's what I have to balance: 


  Solid aluminum bicarbonate and hydrochloric  acid combine to form an aluminum chloride solution and carbonic acid.


Or in an equation form:  

$$\ce{\text{__ } Al(HCO3)3 + \text{__ } HCl -&gt; \text{__ } AlCl3 + \text{__ } H2CO3}$$

Side Note:   

$\ce{Al}$ has a charge of $3+$ and $\ce{(HCO3)}$ has a charge of $1-$. To balance the ionic compound we have to change it to: $\ce{Al(HCO3)3}$.

The underscores before each compound in the chemical equation are just there for number values we can input in order to balance the equation.

My question is: what would be the reactants and products in this chemical equation? Would $\ce{HCO3}$ as a whole compound be a reactant itself?

You give the equation, you just need to balance it. 


  Would HCO3 as a whole compound be a reactant itself?


No, $\ce{HCO3^-}$ is an anion.
