How to balance Cl2(g) + KBr(aq)
zzz [600]

Answer:

Cl₂(g) + 2 KBr(aq) ⇒ Br₂(l) + 2 KCl(aq)

Explanation:

Let's consider the unbalanced single displacement reaction between chlorine and potassium bromide.

Cl₂(g) + KBr(aq) ⇒ Br₂(l) + KCl(aq)

We will start balancing Cl atoms by multiplying KCl by 2.

Cl₂(g) + KBr(aq) ⇒ Br₂(l) + 2 KCl(aq)

Finally, to get the balanced equation, we have to multiply KBr by 2.

Cl₂(g) + 2 KBr(aq) ⇒ Br₂(l) + 2 KCl(aq)
