Answers to Materials science introduction questions.1. (a) Copper is much lower in the electrochemical series (E⦵ = + 0.34 V) compared to tin (E⦵ = − 0.14 V) so is less reactive than tin, i.e. less readily oxidised to its ions.(b) (i) + 2(ii) It will decompose to copper(II) oxide when heated, which can then be reduced with carbon (or another reducing agent such as carbon monoxide or hydrogen).Cu2CO3(OH)2(s) →...
