Please add more information to your post. Can you include phrases such as
"random movement of particles"
"lighter particles"
"heavier particles"
"slow process due to collisions with..."
Words in italics should be corrected.

Diffusion is when particles moves zig-zag

I learnt that the heavier the particles the slower it will move. I also learnt how particles moved in a zig zag motion due to ...................air.

During difusion between HCL and NH3 i learnt that NH3 travels faster because it is twice as light as HCL so NH3 travels to the side of HCL faster.
How do you know this?

I learnt that particles don't move in a straight line they move in a zig zag line. Ammonia is a lighter solution than hydrochloride acid

# data[].attributes.body
During Diffusions the particles move in Zig Zags. I also learnt that ammonia .......acid.......

# data[].attributes.body
Lighter particles travel faster than heavier ones. They move in zig zag shapes because they bounce off the air. Nice.....

# data[].attributes.body
Today I have learnt that when hydrochloride acid and ammonia  gas react, they create something that is called ammononium .......

I learnt that during diffusion the lighter particles move faster than the heavier particles

Smaller particles (ammonia) moves faster than heavier particles (hydrogen chloride). How do you know this?

# data[].attributes.body
The hydrogen chloride gas and the ammonia gas will react together and will make ammonium chloride. The particles of hydrogen chloride are twice as heavy as the particles of ammonia so the particles of ammonia travel faster than the particles of hydrogen chloride. The particles move in a zig zag motion and goes through all of the air particles to get to its destination. When the ammonia and hydrogen chloride particles meet it will be closer to where the hydrogen chloride particles started because the hydrogen particles are slower than the ammonia particles.

The small particle move faster than the heavy one.And the particle move z when there air in the tube.

I learnt that the ammonia solution is a lighter solution and the hydrouchloric acid is a heavier solution so the lighter solution gets to the hydrouchloric acid first and that is when diffusion occurs. While this is happening in the solution the particles are moving really fast in zig zag motions

Acalis are blue and acids are red.

During Diffusion ............move in zig zag, and it happens quite fast.

# data[].attributes.body
I learnt that I could sperate particles easier. I learnt that particles go in zig zag not in a straight line.

# data[].attributes.body
I learnt that ammonia solution is the lighter soloution and the hydrochloc acid is the heavier soloution. While the reaction is occurring the particles are moving extremely fast in a zig zag motion through the air practices. This is called diffusion.
