What is the mathematical expression that allows us to determine the resulting pressure, volume, or temperature after a change in pressure, volume, or temperature?

is hard but tricky at the same time

Explanation:

c is the answer because when something is left after something evaporates that shows the chemical change.

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).
