Solution

(a)

$2 H_{2} S (g) + 3 O_{2} (g) ⟶ 2 S O_{2} (g) + 2 H_{2} O (l)$

(b)

$P_{4} + 5 O_{2} (g) ⟶ 2 P_{2} O_{5}$

(c)

$C S_{2} (s) + 3 O_{2} (g) ⟶ 2 S O_{2} (g) + C O_{2} (g)$

(d)

$F e_{2} O_{3} (s) + 2 A l (s) ⟶ A L_{2} O_{3} (s) + 2 F e (s)$

(e)

$B a C l_{2} + Z n S O_{4} ⟶ B a S O_{4} + Z n C l_{2}$
