A balloon is filled with helium gas has a volume of 750 mL at a pressure of 1 atm. The balloon is released and reaches an altitude if 7,000 m, where the pressure is 0.52 atm. If the
temperature remains the same, what volume does the gas occupy? *
(1 Point)
Use the given equation to solve the question.
P. Vi
P2V2
nRT
n2R72

the atomic number will stay the same no matter how many electrons it has, so it doesn’t decrease nor increase. it’ll only change with a different number of protons

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).
