Solution

The correct option is D P(1, 2, 3, 5); Q(1, 2, 3, 5); R(3, 4, 5); S(3, 4)
$F e S O_{4} Δ - \to F e_{2} O_{3} + S O_{2} + S O_{3}$
$B e S O_{4} Δ - \to B e O + S O_{3} Δ - \to S O_{2} + O_{2}$
$N a N O_{3} > 300^{o} C - --- \to N_{2} + N a_{2} O + O_{2}$
$N H_{4})_{2} C r_{2} O_{7} Δ - \to N_{2} + C r_{2} O_{3} + 4 H_{2} O$
