A tall, horizontally subdivided or packed container for fractional distillation in which vapor passes upward and condensing liquid flows downward. The vapor becomes progressively enriched in more volatile components as it ascends, and the less volatile components become concentrated in the descending liquid, which can be drawn off.
When a system experiences a disturbance ( such as concentration, temperature, or pressure changes), it will respond to restore a new equilibrium state.
Answer:
When you mine, you usually drill the oil whereas you mechanically press oil when you extract it.
Explanation:
hope this helped, sry it took so long.
The ph before the addition of any Koh is<u> 10.105.</u>
Concentration is the abundance of a constituent divided by way of the overall volume of an aggregate. several sorts of mathematical descriptions may be outstanding: mass concentration, molar concentration, variety concentration, and extent awareness.
After the addition of 50 ml KOH,
moles of KOH = 50 * 0.13 =<u> 6.5 mmol </u>
<u>moles </u><u>of HClO = 50 * 0.13 = 6.5 mmol </u>
occurred hydrolysis solution,
pH = 0.5(14 + pKa + log [base conjugate])
pH = 0.5(14 + (- log (4 * 10^-8)) + log (6.5/(50 + 50)))
pH = <u>10.105</u>
The concentration of a substance is the quantity of solute found in a given amount of solution. Concentrations are normally expressed in terms of molarity, defined because of the variety of moles of solute in 1 L of answer.
The Concentration of an answer is a measure of the quantity of solute that has been dissolved in a given amount of solvent or answer. A concentrated answer is one that has a rather huge quantity of dissolved solute.

He can conclude that his experiment has very low precision.
<h3>What is Precision ?</h3>
Precision is defined as the degree of refinement with which an operation is performed or a measurement .
Precision is how close the exact answers are together.
As, the answers are increasing in time.
None of the answers are similar to one another.
Hence, He can conclude that his experiment has very low precision.
