Question

write a balanced chemical equation based on the following description: aqueous silver nitrate reacts with aqueous nickel(ii) chloride to produce solid silver chloride and aqueous nickel(ii) nitrate agno₃(aq) + nicl₂(aq) →

Explanation:

Step1: Write the unbalanced equation

The reactants are \(AgNO_3(aq)\) and \(NiCl_2(aq)\), and the products are \(AgCl(s)\) and \(Ni(NO_3)_2(aq)\). So the unbalanced equation is \(AgNO_3(aq)+NiCl_2(aq)\to AgCl(s)+Ni(NO_3)_2(aq)\)

Step2: Balance the nitrate ions

There are 2 nitrate ions (\(NO_3^-\)) in \(Ni(NO_3)_2\). So we put a coefficient of 2 in front of \(AgNO_3\). The equation becomes \(2AgNO_3(aq)+NiCl_2(aq)\to AgCl(s)+Ni(NO_3)_2(aq)\)

Step3: Balance the silver ions

After putting a coefficient of 2 in front of \(AgNO_3\), there are 2 silver ions (\(Ag^+\)). So we put a coefficient of 2 in front of \(AgCl\). The balanced equation is \(2AgNO_3(aq)+NiCl_2(aq)\to 2AgCl(s)+Ni(NO_3)_2(aq)\)

Answer:

\(2AgNO_3(aq)+NiCl_2(aq)\to 2AgCl(s)+Ni(NO_3)_2(aq)\)
