Question

Write balanced chemical equations for the following double replacement reactions:

a) NaCl + AgNO3 →
b) BaCl2 + Na2SO4 →
c) Pb(NO3)2 + KI →

Answer 1

The balanced chemical equations for the given double replacement reactions are: NaCl + AgNO3 → AgCl + NaNO3, BaCl2 + Na2SO4 → BaSO4 + 2NaCl, Pb(NO3)2 + 2KI → PbI2 + 2KNO3

Step-by-step explanation:

Here are the balanced chemical equations for the given double replacement reactions:

a) NaCl + AgNO3 → AgCl + NaNO3

b) BaCl2 + Na2SO4 → BaSO4 + 2NaCl

c) Pb(NO3)2 + 2KI → PbI2 + 2KNO3

In these reactions, the positive ions in the reactants exchange places to form new compounds. The resulting products are balanced in terms of the number of atoms and charge.
