Question

KI + Cl2 ---> KCl + I2

Balance the single replacement chemical reaction.
A) KI + Cl2 ---> KCl + I2
B) KI + Cl2 ---> 2KCl + I2
C) 2KI + Cl2 ---> 2KCl + I2
D) 2KI + 2Cl2 ---> 2KCl + 2I2


HELPPPPP!!!!

Answer 1

The given equation is

KI + Cl2 ---> KCl + I2.

After balancing the Chemical equation the balanced equation would be

2KI + Cl2 ---> 2KCl + I2.

Hence the correct answer would be C. It can be referred as an oxidation-reduction or redox reaction:

2 I-I - 2 e- → 2 I0 (oxidation), 2 Cl0 + 2 e- → 2 Cl-I (reduction)
