Balancing Chemical Equations (10.1)
71. Write skeleton equations for these reactions.
a. hydrogen iodide(g) → hydrogen(g) + iodine(g)
b. aluminum(s) + iodine(s) — aluminum iodide(s)
c. iron(II) oxide(s) + oxygen(g) -> iron(III) oxide(s)

a. HI(g) ⇒ H₂9g) + I₂(g)

b. Al(s) + I₂(s)⇒AlI₃(s)

c. FeO(s)+O₂(g)⇒Fe₂O₃(s)

Further explanation

Given

word equations

Required

skeleton equations

Solution

The skeleton equation shows the chemical formula of the reaction between reactants and products, regardless of the actual amount of the reacting compound (unbalanced reaction)

The skeleton equations :

a. HI(g) ⇒ H₂9g) + I₂(g)

b. Al(s) + I₂(s)⇒AlI₃(s)

c. FeO(s)+O₂(g)⇒Fe₂O₃(s)
