Four balloons, each with a mass of 10.0 g, are inflated to a volume of 20.0 l, each with a different gas: helium, neon, carbon monoxide, or nitrogen monoxide. if the temperature is 25.0°c and the atmospheric pressure is1.00 atm, what is the density of each filled balloon? (note: the density of the filled balloon refers to both the contents of the balloon and the balloon itself.)

Pressure ,P = 1 atm

Volume, V = 20.0 L

R = 0.0821 atm L/mol K

Balloon 1

Density of balloon 1 =

Balloon 2

Density of balloon 2=

Balloon 3

Density of balloon 3 =

Balloon 4

Density of balloon 4=

yes it is balanced

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).
