In former times, gas volume was used as a way to measure temperature, using devices called gas thermometers. Consider a gas that has volume of 0.675 L at 35 C and 1 atm pressure. What is the temperature ( in c) of a room where the gas has a volume of 0.635 L at 1 atm

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).
