​

Answer 1

Explanation:

i. rust

ii. photosynthesis

iii. in cells batteries

iv. in respiration. O2 to CO2

v. burning

Answer 2

Answer:

(a)CuO(s) + H₂(g) → Cu(s) + H2O(l)

CuO adds oxygen to H₂; CuO is therefore the oxidizing agent or oxidant, it oxidizes the H₂ to H2O.

(b). C(s) + H2O(g) → H₂(g) + CO(g)

H2O is the oxidizing agent; it gives oxygen to carbon, which is oxidized to CO.

Mg+Zn(NO

⟶Zn+Mg(NO

to 0 in Zn.

2Na+Cl

⟶2NaCl

Na is oxidised from 0 to +1 in NaCl. But Cl is reduced from 0 to −1 in NaCl
