In: Chemistry

Write a balanced chemical equation for each of the following descriptions of chemical reactions, including state symbols:

a. Aluminum metal reacts with aqueous iron(II) chloride to form aqueous aluminum chloride and iron metal.

b. Solid cobalt (III) oxide reacts with solid carbon to produce solid cobalt and carbon dioxide gas.

c. Nitrogen dioxide gas reacts with gaseous oxygen and liquid water to form aqueous nitric acid.

Expert Solution

Aluminum metal: Al(s)

aqueous iron(II) chloride: FeCl2(aq)

aqueous aluminum chloride: AlCl3(aq)

iron metal: Fe(s)

a) Al(s) + FeCl₂(aq) ---> AlCl₃(aq) + Fe(s)

After balancing the equation

2Al(s) + 3FeCl₂(aq) ---> 2AlCl₃(aq) + 3Fe(s)

b)

Solid cobalt (III) oxide: Co₂O₃(s)

solid carbon: C(s)

solid cobalt : Co(s)

carbon dioxide gas: CO2(g)

2Co₂O₃(s) + 3C(s) ---> 3CO2(g) + 4Co(s)

C) Nitrogen dioxide gas: NO₂(g)

gaseous oxygen; O₂(g)

liquid water: H₂O(l)

aqueous nitric acid: HNO₃(aq)

4NO₂(g) + O₂(g) + 2H₂O(l) ---> 4HNO₃(aq)
