The commercial production of nitric acid involves the following chemical reactions: 4 NH3 (g) + 5 O2 (g) → 4 NO (g) + 6 H2O (g)
2 NO (g) = O2 (g) → 2 NO2 (g)
3 NO2 (g) + H2O (l) → 2 HNO3 (aq) + NO (g)
Which of these reactions are redox reactions?

In each redox reaction identify the element undergoing oxidation and the element undergoing reduction.

it is a good conductor

explanation:

answer: -

reaction:

na + cl ⇌ nacl

balanced chemical equation:

na + 2cl ⇌ nacl2

sodium + clorine goes to form sodium chloride (table salt).

the product is nacl2.

and the reactants are na and cl.

(note: if you don’t know what ⇌ means, read below: -

⇌(double head arrow) means reversible reaction).

a 20-cm-long, cylindrical graphite (pure carbon) rod is inserted into an oxidizing atmosphere at 1145 k and 1.013 x 105 pa pressure. the oxidizing process is limited by the diffu- sion of oxygen counterflow to the carbon monoxide that is formed on the cylindrical surface.
