Write the full balanced chemical equation for each of the following. Include phase labels on all species.

a. Solid iron (III) oxide is formed from its elements at room temperature.

b. Solid iron (III) oxide reacts with carbon graphite (solid carbon) to form solid iron metal and gaseous carbon monoxide.

c. Solid copper (II) oxide is dissolved in liquid hydrogen chloride and forms solid copper (II) chloride and liquid water.

d. When reacted with elemental chlorine at room temperature, liquid phosphorous trichloride (PCl3) is converted to solid phosphorous pentachloride (PCl5).

Solutions

Expert Solution

Ans :

To write the full balanced reactions for chemical processes , we start by writing down the skeletal equation alongwith the physical states mentioned in their parenthesis.

Then the element on each side are equated.

So here , the balanced reactions are given as :

a) 4Fe(s) + 3O2 (g) = 2Fe2O3 (s)

b) Fe2O3 (s) + 3C (s) = 2Fe (s) + 3CO (g)

c) CuO (s) + 2HCl (l) = CuCl2 (s) + H2O (l)

d) Cl2 (g) + PCl3 (l) = PCl5 (s)
