Correct answer
A2,5 and 16

Step-by-step explanation

C 2 O 4 2 - ⟶ 2 CO 2 + 2 e - ] × 5 MnO 4 - + 8 H + + 5 e- ⟶ Mn 2 + + 4 H 2 O ] × 2
-----------------------------------------------------------------------------------
2 MnO 4 - + 1 6 H + + 5 C 2 O 4 2 - ⟶ 1 0 CO 2 + 2 Mn 2 + + 8 H 2 O

MnO 4 - ⇒ x = 2

C 2 O 4 2 - ⇒ y = 5

H + ⇒ z = 1 6
