At constant pressure, when the temperature of a gas is decreased, what happens to its volume? A. it remains constant
B. it will vary
C. it decreases
D. it increases

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).
