Question

0.2. Answer the following any three). Identify reductants and oxidants in the following reactions.
4NH3+ 5O2= 4NO+6H2O​

Answer 1

Answer:

O2-oxidant

NH3-reductant

Answer 2

Here is full explain---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.Read more on Sarthaks.com - https://www.sarthaks.com/2185/identify-the-reducing-agent-in-the-following-reactions-i-4nh3-5o2-4no-6h2o
