A 10 g sample of liquid nitrogen and a 10 g sample of gaseous nitrogen have different densities, yet they are both nitrogen -- just in a different state of matter (one is a liquid and one is a gas). Which form of nitrogen has a larger volume? Why?

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).
