Question

Write the skeletal equation and balanced equation for the following reaction:

Potassium bromide (aq) + Barium iodide (aq) → Potassium iodide (aq) + Barium bromide (s)

Answer 1

Skeletal Equation: KBr(aq) + BaI₂(aq) → KI(aq) + BaBr₂(s) 

Balanced Equation: 2KBr(aq) + BaI₂(aq) → 2KI(aq) + BaBr₂(s)

Verification: 

There are 2 atoms of K present in LHS and 2 atoms in RHS. Similarly, atoms of I, Br, Ba are also the same in both sides. This is what a balanced equation means
