3. How can you decrease the pressure of a gas in a container without changing the volume of the gas? add more gas particles to the container
move the container to a lower altitude
o o
reduce the temperature of the gas
O
change the shape of the container

reduce the temperature of the gas

Explanation:

when you reduce the temperature of the gas the pressure will decrease

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).
