Question

for the following single replacement reaction, complete the reaction including the correct products.
mg + pbcl₂ →
+
cl₂
mgcl₂
mgpb
pb
pb₂

Explanation:

Step1: Understand single - replacement reaction

In a single - replacement reaction \(A + BC
ightarrow AC + B\), where \(A\) is more reactive than \(B\). Here \(Mg\) is more reactive than \(Pb\) (from the activity series of metals).

Step2: Determine the products

When \(Mg\) reacts with \(PbCl_{2}\), \(Mg\) replaces \(Pb\). The formula for the chloride of \(Mg\) is \(MgCl_{2}\) (since \(Mg\) has a \(+ 2\) charge and \(Cl\) has a \(-1\) charge) and the product for the metal is \(Pb\) (in its elemental form).

Answer:

\(MgCl_{2}+Pb\)
