Question

Balance the equation MnO2 + HCl → Cl2 + MnCl2 + H2O?

using the smallest possible integer coefficients.

What is the sum of the coefficient?

1. 12
2. 15
3. 9
4. 7
5. 26

Answer 1

Answer:9

Step-by-step explanation:

MnO2+4HCl------->MnCl2 + 2H2O + Cl2

This gives 1+4+1+2+1=9

This is the smallest sum of integer coefficients needed to balance the equation as shown.
