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:
B
Explanation:
it is the energy stored in the chemical bonds of a substance
Answer:
b. .28 M KCI
Explanation:
Use the dilution formula.
C₁V₁ = C₂V₂
C₂ = C₁V₁/V₂
C₂ = 1.6*0.175 / 1.0
C₂ = 0.28
37.8 g CH2Br2 X (1 mol CH2Br2 / 173.83 g) = 4.60X10^-3 mol CH2Br2
<span>4.60X10^-3 mol CH2Br2 X (2 mol Br / 1 mol CH2Br2) X 6.02X10^23 atoms/mol = 5.54X10^21 bromine atoms.
I think this is the answer.</span>
