Final answer:
In the reaction 2Al(s) + 6HCl(aq) = 2AlCl3(aq) + 3H2(g), the physical states are: Reactants - Al(s) (solid) and HCl(aq) (aqueous solution), Products - AlCl3(aq) (aqueous solution) and H2(g) (gas).
Step-by-step explanation:
The physical states of the substances involved in the reaction 2Al(s) + 6HCl(aq) = 2AlCl3(aq) + 3H2(g) can be determined by looking at their symbols in the chemical equation. The symbol (s) represents a solid, (aq) represents a substance dissolved in water, and (g) represents a gas.
In this reaction, 2Al(s) and 6HCl(aq) are the reactants. Al(s) is solid aluminum, and HCl(aq) is an aqueous solution of hydrochloric acid. The products 2AlCl3(aq) and 3H2(g) indicate that aluminum chloride is a dissolved substance and hydrogen gas is in gaseous form.
So, the physical states in this reaction are:
Reactants: Al(s) (solid) and HCl(aq) (aqueous solution)
Products: AlCl3(aq) (aqueous solution) and H2(g) (gas)
