A box containing a piece of wood and enough air to burn the wood is measured and found to have a mass of 1.5 kg. If the wood is burned and none of the smoke, ashes, or hot gases are allowed to leave the box, then how will the mass of the box compare to the mass before burning? Will it be more, less, or the same?

how to make a simple air condition

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).
