Question

KI + Cl2 ---> KCl + I2
Balance the single replacement chemical reaction.

Answer 1

2KI + Cl₂ → 2KCl + I₂

Step-by-step explanation:

The reaction equation is given as:

KI + Cl₂ → KCl + I₂

The problem at hand is to balance this chemical reaction. To solve this problem we use a mathematical approach;

aKI + bCl₂ → cKCl + dI₂

Conserving K : a = c

I : a = 2d

Cl : 2b = c

Now let a = 1, c = 1 , d =
`(1)/(2)`, b =
`(1)/(2)`, ;

Multiply through by 2;

a = 2, b = 1 , c = 2, d = 1

2KI + Cl₂ → 2KCl + I₂
