A student used the set-up shown in the diagram below in order to study the reactions of some metals with steam. The experiment was carried out for ten minutes.

a) What observation would be made if gas H was ignited.
b) When the experiment was repeated using lead powder instead of Beryllium very little of gas H was obtained. Give a reason for this observation.
c) Name another gas which is used together with hydrogen in welding.

---

a) The gas burns with a ‘pop’ sound

b) Lead is least reactive compared to Berylium thus the reaction is slow hence little amount of hydrogen gas.

c) Oxygen
