3. Adam wishes to make a battery which can generate electrical energy from the following
reaction:
Fe$O, (aq) + Mg(s) - MgSO (aq) + Fe(s)
As well as access to all common laboratory
equipment, Adam also has the following
chemicals at his disposal:
an aqueous solution of Feso. (1 M)
an aqueous solution of MgSO, (1 M)
an aqueous solution of KNO,
strips of Mg metal and Fe metal
Draw a labelled diagram to show how Adam
could use the above materials to generate a
battery and measure its voltage. Identify the
laboratory equipment he will need.

i think it is d. e because the next one is igneous.

the electrical  conductivity  of asolution  of an electrolyte is measured by determining the resistance of thesolution  between two flat or cylindrical electrodes separated by a fixed distance.

nacl or sodium chloride is an ionic compound. this is because an ionic compound pertains to a compound that consists of positively and negatively charged ions. in this case, na (sodium) has a tendency to lose one electron when it reacts with with other atoms, so the resulting sodium ion contains 11 protons and 10 electrons, thus making it positively charged (na+), when chlorine reacts, it usually gains one electron to form an ion called chloride, thus making it negatively charged ( since the ions are oppositely charged, they attract.
