In some foam-type fre extinguishers, the treactants are `Al_2 (SO_4)_3` (aq) and  `NaHCO_3` (aq). T=When the extinguisher is activated, these reactants are allowed to mix producing `Al(OH)_(3(s))` and ` CO_(2(g))`.  The ` al (OH)_3 - CO_2` foram extinguishes the fires .  Addition of `Na_2 CO_3` to a solution of an oxide in eater produces `CO_2`. This experiment indicaltes that :
