WebDespite being a non-metal, hydrogen is often included in the reactivity series since it helps compare the reactivities of the metals. The metals placed above hydrogen in the series can displace it from acids such as HCl and … WebSep 16, 2024 · When solid copper (I) oxide is heated with hydrogen, for example, its mass decreases because the formation of pure copper is accompanied by the loss of oxygen atoms as a volatile product (water vapor). The reaction is as follows: (4.4.1) Cu 2 O ( s) + H 2 ( g) → 2 Cu ( s) + H 2 O ( g)
