used in the experiment. Q3. Nickel is a transition element. It is manufactured in a four-stage process from nickel (II) sulphide‚ NiS. • Stage 1 – nickel (II) sulphide is heated in air to form nickel (II) oxide and sulphur dioxide. • Stage 2 – nickel (II) oxide is heated with carbon to give impure nickel. • Stage 3 – impure nickel is reacted with carbon monoxide to make nickel tetracarbonyl‚ Ni (CO)4. • Stage 4 – nickel tetracarbonyl is decomposed to give pure nickel.

TRANSDUCERS Transducers are electric or electronic devices that transform energy from one form to another. A transducer is a device that converts one form of energy to other form. It converts the measureand to a usable electrical signal. In other word it is a device that is capable of converting the physical quantity into a proportional electrical quantity such as voltage or current.
