Question

Nitric oxide acts as a reducing agent in the reaction
(a) 4NH3 +502 → 4NO+6H20
(b) 2 NO +312 +4H20--2NO3 +61 +8H+
(c) 2NO+H2SO3 → N20+H2SO4
(d) 2 NO+ H2S → N20+S+H204
......and plz explain it..
i will mark u as brainlist..!!​

Answer 1

Answer:

4NH3+5O2→4NO+6H2O

Reducing agent is the one which reduces other substance(by removal of oxygen or addition of hydrogen) and itself gets oxidised.

In the above reaction, ammonia(NH3) is the reducing agent as it is being oxidised by oxygen (O2) form nitric oxide (NO) and water (H 2O).

hope this help u !!!

Answer 2

Answer:

i. NH3 gets oxidized to NO (Removal of hydrogen, addition of oxygen) O2 gets reduced to H2O ( Addition of hydrogen).

Thus, NH3 acts as reducing agent.

ii. F2 gets reduced to HF (Addition of hydrogen) H2O gets oxidized to HOF (Removal of hydrogen)

Hence, H2O acts as reducing agent.

iii. Fe2O3 gets reduced to Fe (Removal of oxygen) CO gets oxidized to CO2 (Addition of oxygen)

Hence, CO acts as reducing agent.

iv. H2 gets oxidized to H2O (Addition of oxygen) O2 gets reduced to H2O (Addition of hydrogen)

Hence, H2 acts as reducing agent.
