How many moles of aluminum are needed to react with 3.6 mol of feo? 2al(s) + 3feo(s) → 3fe(s) +al₂o₃(s)

Solid – In a solid, the attractive forces keep the particles together tightly enough so that the particles do not move past each other. Their vibration is related to their kinetic energy. In the solid the particles vibrate in place.

Liquid – In a liquid, particles will flow or glide over one another, but stay toward the bottom of the container. The attractive forces between particles are strong enough to hold a specific volume but not strong enough to keep the molecules sliding over each other.

Gas – In a gas, particles are in continual straight-line motion. The kinetic energy of the molecule is greater than the attractive force between them, thus they are much farther apart and move freely of each other. In most cases, there are essentially no attractive forces between particles. This means that a gas has nothing to hold a specific shape or volume. Here is the link for that. http://web.fscj.edu/Milczanowski/psc/lect/Ch4/slide2.htm

-Gas assumes the shape and volume of its container (particles can move past one another)

-Compressible (lots of free space between particles)

-Flows easily (particles can move past one another)

Liquid

-Assumes the shape of the part of the container which it occupies (particles can move/slide past one another)

-Not easily compressible (little free space between particles)

-flows easily (particles can move/slide past one another)

Solid

-Retains a fixed volume and shape (rigid - particles locked into place)

-Not easily compressible (little free space between particles)

-Does not flow easily (rigid - particles cannot move/slide past one another)
