Write the balanced equation for the preparation of Iron(II) sulphate starting from iron and using only one another substance.

Write balanced reactions for the following conversions (A, B, C, D)

$\mathrm{Fe}\stackrel{\mathrm{A}}{\to }{\mathrm{FeCl}}_2\stackrel{\mathrm{B}}{\to }{\mathrm{FeCO}}_3\stackrel{\mathrm{C}}{\to }\mathrm{Fe}{\left({\mathrm{NO}}_3\right)}_2\stackrel{\mathrm{D}}{\to }\mathrm{Fe}{\left(\mathrm{OH}\right)}_2$

The preparation of lead sulphate from lead carbonate is a two-step process. (lead sulphate cannot be prepared by adding dilute sulphuric acid to lead carbonate.)

(a) What is the first step that is required to prepare lead sulphate from lead carbonate?

(b) Write the equation for the reaction that will take place when this first step is carried out.

(c) Why is the direct addition of dilute sulphuric acid to lead carbonate an impractical method of preparing lead sulphate?
