Question

Write the balanced chemical equations for the following double-replacement reactions.

Answer 1

The balanced equation :

LiI(aq) + AgNO₃(aq) --> AgI(s) + LiNO₃(aq)

Further explanation

Given

Word equation

Required

Balanced equation

Solution

There are 3 ways to express a chemical equation:

• word equation
• skeleton equation
• balanced equation

Skeleton equation for reaction above :

LiI(aq) + AgNO₃(aq) ⇒ AgI(s) + LiNO₃(aq)

If we look at this reaction, all the cations and anions have a charge of 1 (+1 or -1) so the balanced reaction between the skeleton equation and the balanced equation is the same
