Question

iv) Fe +
+
O2
Fe2O3 the explain​

Answer 1

2Fe +O2+H2O arrow- Fe2O3+H2

Explanation:

fe2O3(rust of iron) rust of iron obtained from reaction between iron and oxygen and water( humidity)

Answer 2

Answer:

Fe + O2 → Fe2O3 is the unbalanced form of chemical reaction.

Balancing the simple molecules first, in this case the O2

Fe + 3O2→ Fe2O3 there are now 6 O atoms on the left, there must also be 6 O atoms on the right.

Fe + 3O2 → 2Fe2O3

Balance the rest of the equation:

4Fe + 3O2→ 2Fe2O3
