The balloons below are filled with helium gas. Which of the balloons best represents the diffusion of helium gas within the ballloon
and why?
Balloon B because Helium is a dense gas that will collect at the bottom of the balloon.
Balloon A because the gas particles will only take the shape of the container and put pressure on
the walls.
Balloon D because gas particles are less dense and will make the balloon float.
Balloon C because gas particles diffuse to take the shape and volume of their container.

First up write the aim
then write the materials reqd.
then the procedure which you follow
then observation
then conclusion
then you can write lab safety rules or precautions(you can avoid if u want).
lemme' give an example
aim: to observe the double displacement reaction
materials reqd: bacl2 and na2so4, test tubes and a dropper
procedure:
1. take bacl2 in a test tube and na2so4 in the other.
2. then pour bacl2 into na2so4 solution.
3. observe
observation:
you will see that a white precipitate is formed called baso4. along with that common salt or nacl is formed.
the equation is
bacl2+na2so4=baso4+2nacl
conclusion:
a double displacement reaction is observed.
hope it
