Answer:
The answer lays in logD.
Explanation:
So when you end up with neutral pH amine or either carboxylic acid can still be in a salt form. So for every compound the pH level of unionized form is different and for the best extraction experience is better to perform and extraction at as low as possible pH for acids and for amines as high as possible.
Answer:
2.78 moles of water are produced.
Explanation:
Given data:
Number of moles of H₂O produced = ?
Number of moles of oxygen react = 3.25 mol
Solution:
Chemical equation:
2C₂H₆ + 7O₂ → 4CO₂ + 6H₂O
Now we will compare the moles of water with oxygen.
O₂ : H₂O
7 : 6
3.25 : 6/7×3.25 = 2.78 mol
b. carbon-12
c. uranium-236
d. uranium-238
Answer:
Explanation:
Temperature is also known as the average kinetic energy in a substance.
If there is an absence of heat in a substance, the particles move slower and the kinetic energy decreases. The temperature will be lower, because there is less kinetic energy.
If heat is present or applied, the particles move more, so kinetic energy increases. The temperature will be higher, since there is more kinetic energy.
So, the relationship is: temperature is the measure of average kinetic energy.
