Question

HCl+KMnO4=Cl2+MnCl2KCl+H2O

Answer 1

8HCl+KMnO4=3Cl2+MnCl+KCl+4H2O
2Cl(-1) -2e=Cl2(0)    |6|3
Mn(+7) +6e=Mn(+1) |2|1
в скобках я писала степень окисления

Answer 2

The balanced chemical equation for the reaction between hydrochloric acid (HCl) and potassium permanganate (KMnO4) is:

16 HCl + 2 KMnO4 → 5 Cl2 + 2 MnCl2 + 2 KCl + 8 H2O

This equation shows that for every 16 moles of HCl and 2 moles of KMnO4, 5 moles of Cl2, 2 moles of MnCl2, 2 moles of KCl, and 8 moles of H2O are produced.

It is important to note that this reaction is typically carried out under specific conditions, such as heating, to ensure complete reaction and to prevent side reactions. Additionally, this reaction should be carried out with caution, as it produces toxic chlorine gas (Cl2).
