Wildfires are a. a human source of air pollution b. a natural source of air pollution c. both a natural and human source of air pollution d. none of the above

c.  both a natural and human source of air pollution

Explanation:

Wildfires can be produced both by humans (on purpose or not), and naturally (for example when a light strikes a tree).

The smoke produced (despite the origin of the wildfire) pollutes the surrounding air.

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).
