Explanation:
so, as you move down a group on the periodic table, the electronegativity of an element decreases because the increased number of energy levels puts the outer electrons very far away from the pull of the nucleus. electronegativity increases as you move from left to right across a period on the periodic table.
Well if anything was mixed in it would make his result different. if not, it could have changed the temperature when he mixed it. which would give him either a lower or higher answer
Avogadro's number tells you that in one mol of element (sulfur) there are 6.022x10^23 atoms...
So,
1 mol : 6.022x10^23 = x mol : 1.2x10^2
x = 1.99 x 10^-22 mol
*Although this should be correct, you might want to check your question again. You probably misinterpret the question... you want 1.2x10^23 !! :) check it.
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>
