Question

1. we have observed that zinc is capable of replacing lead in a single replacement reaction. build the chemical equation for the single replacement reaction between aqueous lead(ii) nitrate and zinc metal. i need a hint ab + c → cb + a choices: zn zn²⁺ zn₂ pb(no₃)₂ znno₃ zn(no₃)₂ pb pb₂

Explanation:

Step1: Identify reactants

The reactants are aqueous lead(II) nitrate ($\text{Pb(NO}_3)_2$) and zinc metal ($\text{Zn}$).

Step2: Determine products

In a single - replacement reaction, zinc will replace lead. Zinc forms a +2 ion, so the product will be zinc nitrate ($\text{Zn(NO}_3)_2$) and lead metal ($\text{Pb}$).

Step3: Write the chemical equation

$\text{Pb(NO}_3)_2(aq)+\text{Zn}(s)
ightarrow\text{Zn(NO}_3)_2(aq)+\text{Pb}(s)$

Answer:

$\text{Pb(NO}_3)_2(aq)+\text{Zn}(s)
ightarrow\text{Zn(NO}_3)_2(aq)+\text{Pb}(s)$
