Which of the following best represents a balanced equation for the reaction of
nitrogen gas and oxygen gas to form nitrogen monoxide?

The answer to your question is: letter a

Explanation:

a) This answer is correct because nitrogen and oxygen are diatomic.

b) This answer is incorrect because nitrogen and oxygen are monoatomic and the reactants in this reaction are not monoatomic.

c) This answer is incorrect because oxygen is diatomic and in this reaction is not.

d) This option is incorrect because nitrogen is diatomic and in this reaction is not.

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.
