A hot air balloon is filled with 3L of air and it exerts a pressure of 250kPa 25 points against the walls of the balloon. When air is released, the pressure of the
hot air balloon drops to 150kPa. Find the 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).

they are made of gases.

they have a spherical shape.

they make energy through fusion.
