Question
Write a word equation for each redox reaction. Then, using the ideas above, say which sub-
stance is being oxidised, and which is being reduced, in each reaction:
a. Ca (s) + O₂(g) → 2 Cao (s)
b. 200 (g)
+ O2(g) → 2 CO₂(g)
c. 2CuO (g)
+ C(s)→ 2Cu(s) + CO₂(g)
d. 2 Mg (s) + CO₂(g) → 2MgO (s) + C(s)
e. NaOH(aq) + HCl(aq) → NaCl(aq) + H₂0 (1)
