Attempt 14 A semipermeable membrane separates two aqueous solutions at 20 ∘ C. For each of the cases, determine the direction, if any, of the net flow of water. Assume 100% dissociation for electrolytes, meaning ion pairing can be ignored.

List four observations that indicate that a chemical reaction may be taking place

The atoms of a solid aluminum can are close together, vibrating in a rigid structure. if the can is warmed up on a hot plate, what happens to the atoms?

How is energy related to the change of state represented by the model? atoms gain energy as a solid changes to a liquid. atoms gain energy as a solid changes to a gas. atoms lose energy as a solid changes to a liquid. atoms lose energy as a solid changes to a gas.
