Question

the following molecular equation represents the reaction that occurs when aqueous solutions of lead(ii) nitrate and manganese(ii) bromide are combined. pb(no₃)₂(aq)+mnbr₂(aq)→pbbr₂(s)+mn(no₃)₂(aq) write the balanced net ionic equation for the reaction. (use the lowest possible coefficients. be sure to specify states such as (aq) or (s). if a box is not needed, leave it blank.)

Explanation:

Step1: Write the complete ionic equation

$$\text{Pb}^{2+}(aq)+2\text{NO}_3^-(aq)+\text{Mn}^{2+}(aq)+2\text{Br}^-(aq)\to\text{PbBr}_2(s)+\text{Mn}^{2+}(aq)+2\text{NO}_3^-(aq)$$

Step2: Cancel the spectator ions

Spectator ions are $\text{Mn}^{2+}(aq)$ and $\text{NO}_3^-(aq)$
$$\text{Pb}^{2+}(aq)+2\text{Br}^-(aq)\to\text{PbBr}_2(s)$$

Answer:

$$\text{Pb}^{2+}(aq)+2\text{Br}^-(aq)\to\text{PbBr}_2(s)$$
