Hydrogen + Lead(II) oxide burns brightly. Yellow Lead is produced.
lead(II) powder changes to shiny grey. Hydrogen reduces
oxide lead(II) oxide to lead.

Hydrogen + Copper(II) oxide burns very brightly. Copper is produced.
copper(II) Black powder changes to brown. Hydrogen reduces
oxide copper(II) oxide to
copper.

(b) Aluminium and zinc are more reactive than hydrogen.
(c) Iron, lead and copper are less reactive than hydrogen.

Conclusion on the Position of Carbon and Hydrogen in the Reactivity Series of
Metals
1. The reactivity series is the arrangement of metals based on their reactivity towards
oxygen. Even then, the position of non-metals like carbon and hydrogen are also
listed in the reactivity series.
2. The position of carbon and hydrogen in the reactivity series of metals:
