Question

.Identify the reducing agent in the following reactions.

a) 4NH3+502 → 4NO + 6H2O

b) H2O + F2 → HF + HOF

c) Fe2O3 + 3CO → 2Fe + 3CO2​

Answer 1

Answer:

4NH3+5O2=4NO+6H2O? This reaction is an oxidation-reduction or 'redox' reaction. The formal oxidation state of oxygen in dioxygen (O2) is zero on the left-hand side. It is -2 in water on the right hand side

ok mark as me a brainliest pls

Answer 2

Answer:

a) NH3 is reducing agent.

b) F2 is the reducing agent as it takes away O2 from H2O.

c) 3CO is reducing agent as it takes away O2 from Fea2CO3.
