A gas jar full of air was placed upside down on a gas jar full of bromine vapours, the red brown vapours of bromine moved from the lower jar to the upper jar conntaining air. in this experiment

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).

the answer is minerals.
