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:
$$\ce{\text{__ } Al(HCO3)3 + \text{__ } HCl -> \text{__ } AlCl3 + \text{__ } H2CO3}$$
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?
