Materials are transferred between individual cells and their internal environment through the cell membrane by diffusion, osmosis, and active transport. During diffusion and osmosis, molecules move from a higher concentration to a lower concentration. Osmosis: Osmosis is the movement of solvent particles across a semipermeable membrane from a dilute solution into a concentrated solution. Diffusion: Diffusion is the movement of particles from an area of higher concentration to lower concentration. This would be the diffusion.

In which sample of water do the water particles have more energy: 5 grams of ice cubes at -10 degrees Celsius or 5 grams of liqu

Ivenika [448]

Higher temperature = higher energy. In water it is a liquid as the particles have more energy so vibrate and are further away from each other.

When water breaks apart an ionic compound into cations and anions:

liq [111]

Answer:
Dissociation

Explanation:
The molecule of water is polar. This means that the hydrogen has a partial positive charge while the oxygen has a partial negative charge.
Ionic compounds have equal number of positive and negative charges.
When these compounds are placed in water, the partial positive hydrogen starts to attract the negative ion of the ionic compound while the partial negative oxygen starts to attract the positive ion of the ionic compound.

This process is called dissociation and leads to the breaking of ionic compound into cations and anions in water.

Hope this helps :)
