Predict two physical properties of zinc bromide, besides electrical conductivity.
Zinc and bromine react to produce zinc bromide. $\text{Zn} + \text{Br}_2 \rightarrow \text{ZnBr}_2$. Zinc bromide contains $\text{Zn}^{2+}$ and $\text{Br}^-$ ions. Explain, in terms of the movement of electrons, how $\text{ZnBr}_2$ is made from zinc atoms and bromine molecules.
Aqueous zinc bromide reacts with magnesium, as shown: $\text{Zn}^{2+} + \text{Mg} \rightarrow \text{Mg}^{2+} + \text{Zn}$. Use the equation to show that oxidation occurs.
Use the equation to show that reduction occurs.
Because zinc carbonate is insoluble in water, it can be made by reacting aqueous zinc bromide with $\text{CO}_3^{2-}(aq)$ ions in a precipitation reaction. Name a suitable aqueous solution that could supply $\text{CO}_3^{2-}(aq)$ ions.
A sample of zinc carbonate is strongly heated. Name the products of this reaction.
