Question

Alex made some iron sulfide and placed it in a circuit with a cell and a lamp what property was alex investigating

Answer 1

Explanation:

Alex was investigating the property of electrical conduction.

Some solutions acts as conductors and have the ability to let electric current pass through them. Now Alex used a cell ( a power source ) and a lamp, an indicator to see if the the solution of iron sulpide will pass the current, then the lamp will grow otherwise the circuit will not complete is iron sulphide would not allow passage of electrons
