Answer:
Kp = 13.3
Explanation:
Partition coefficient is used to extract or purify a solute from a solvent selectively to avoid interference from other substances. The formula is:
Kp = Concentration of solute in organic solvent / Concentration of solute in H₂O
As the CH₂Cl₂ is containing 31mg, water is containing 4mg. Replacing in the formula:
Kp = (31mg/7mL) / (4mg/12mL)
<h3>Kp = 13.3</h3>
Answer:
It's the third option
Explanation:
Because the particles of the solid are very closed together and packed they can barely move, causing the item to have a fixed shape and volume.
Water has a specific type of bonds but has change the temperature its density will vary somewhat. properties such as appearance and solubility, and melting point.
Answer:
4) They are substances.
Explanation:
Compounds are substances that are made up of two or more kind of atoms that are chemically bonded together.
The properties of a compound is distinct and different from those of the individual elements that combines to make it up.
What then is a substance?
Any matter be it solid, liquid or gas with a specific composition is a substance. For example, NaCl is common salt and its chemical properties are uniform in all parts but sea water is not a substance as it is made up of water, mineral salts, dissolved gases etc.
