A balloon is filled with air at a pressure of 105 kPa. Then the pressure around the balloon is increased to 205 kPa. If the balloon had an original
volume of 4.11 L, what is the new (final) volume? *

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).

i believe the answer is three water molecules
