Answer 1

Which property of hydrogen is shown by

the following reactions?

(i) Fe304 + 4H2 -------> 3Fe+4H20

Zno

(ii) CO+H2-------------------> CH3OH

Cr₂O₃

⭕a) Reducing character

⭕b) Oxidising character

⭕c) Combustibility

☑️d) High reactivity

Hope you got it

Answer 2

I)

d) high reactivity OR a) Reducing Character

—as it displaces iron — O is removed

II)

a) Reducing character

— as hydrogen is added

and if you want combined answer

it's

a) Reducing character

as in first Oxygen is removed and in second Hydrogen is added

and in second it's ZnO3 instead of ZnO
