a tank contains l of pure water. brine that contains g of salt per liter of water is pumped into the tank at a rate of l/min. the concentration of salt after minutes can be shown to be given by: what happens to the concentration as ?
The concentration as t continues indefinitely is that it approaches 30 gms/L.
What is concentration measured by?Concentration is a measurement of how much solute there is per volume of solution. In chemistry, concentration is most frequently expressed in molarity by units of molar (M), that is moles per liter solution. Concentration measures the amount of a substance dissolved in a volume of another substance. This can be measured in moles per liter, also called molarity.
In this case, after t minutes, 25t liters of brine have been pumped into the tank, and it makes the volume in the tank is 5000 + 25t liters. Later, after t minutes, those 25t liters of brine have added (25t L) 30 g L = 750t g of salt. So the concentration of salt after t minutes will be:
C(t) = 750t / 5000 + 25t
= 25 * 30t / 25 (200 + t)
= 30t / 200 + t
Thus, to see what happens to the concentration as t → ∞ we need to compute:
lim t → ∞ 30t / 200 + t
= lim t → ∞ (30t * 1/t) / (200 + t) * 1/t
= lim t → ∞ 30 / (200/t + 1)
= 30

Large tides, called spring tides, are experienced in the Earth's oceans when the Moon is in position C A and C.
What are large tides?Large tides, also known as spring tides, are the highest and lowest tides experienced in the Earth's oceans. They occur when the gravitational forces of the Moon and Sun are aligned, either on the same side of the Earth or on opposite sides. This alignment results in a combined gravitational pull on the Earth's oceans, causing the tides to rise to their maximum height and then fall to their minimum height.
Spring tides occur twice a month, during the full moon and new moon phases, and they have a greater tidal range than the more common, intermediate tides known as neap tides. The height of the tides is affected by a number of factors, including the size and shape of the ocean basin, the depth of the water, and the coastlines and ocean currents.
It is important to note that the term "spring tide" has nothing to do with the season of spring, but rather is derived from the Old English word "springan," which means to "leap up."

a chemist dilutes 78.6 ml of 4.97 m sodium chloride to make a 1.8 m solution. what is the final volume of the diluted solution (in ml)?
A chemist creates a 1.8 m solution by diluting 78.6 ml of 4.97 m sodium chloride. The final volume of the diluted solution is 220.44 ml.
The concentration of a solution can be increased by adding solvent or decreased by adding solute. To dilute a solution, you add solvent, which increases the volume of the solution. The new concentration is determined by the ratio of solute to solvent before and after dilution. To find the final volume of the diluted solution, you need to determine the amount of solute (in this case, sodium chloride) and the desired concentration of the solution after dilution. The number of moles of solute can be found using the formula moles = (concentration)(volume). Then, using the formula [tex]M_1V_ = M_2V_2[/tex], you can find the final volume of the diluted solution, given the number of moles of solute, the initial concentration, and the desired final concentration.
[tex]C_1V_1 = C_2V_2[/tex], where [tex]C_1[/tex] and [tex]V_1[/tex] are the concentration and volume of the original solution, and [tex]C_2[/tex] and [tex]V_2[/tex] are the concentration and volume of the diluted solution.
We can plug in the values:
[tex](4.97*78.6) = 1.8*(V_2)[/tex]
⇒ [tex]V_2 = \frac{(4.97*78.6)}{1.8}[/tex]
⇒ [tex]V_2 = 220.44 ml[/tex]
So, the final volume of the diluted solution is 220.44 ml.

would you predict the energy difference between a secondary and a tertiary carbocation to be more or less than 27 kcal/mole?
Prediction of the exact energy difference between a secondary and tertiary carbocation is impossible.
It is not possible to predict the exact energy difference between a secondary and tertiary carbocation with certainty, as it can vary based on several factors such as the structure and stability of the carbocations, solvent effects, and other environmental factors.
However, it is generally accepted that tertiary carbocations are more stable than secondary carbocations, which in turn are more stable than primary carbocations.
This stability is due to hyperconjugation and other stabilizationizing mechanisms, which contribute to a decrease in the energy of the system.
The exact energy difference between secondary and tertiary carbocations can therefore be less than 27 kcal/mol, but the exact value would depend on the specific circumstances.

Drag The Appropriate Items To Their Respective Bins. Reset Help Partial Pressure Temperature Average Kinetic Energy Molar Mass Electronegativity Atom Size Average Velocity Common
The common things in all gases are temperature, average kinetic energy, and average velocity. The different thing about gases is their masses.
What impact does temperature have on the typical kinetic energy of gas molecules?A gas's temperature directly relates to the average kinetic energy of its particles. The particles must travel more quickly as the gas warms since their mass is constant.
What connection exists between temperature and typical kinetic energy?The average kinetic energy of a substance's particles is directly inversely correlated with its temperature. As the temperature rises, the particles must move more quickly because their mass is constant.
What happens to a sample of matter's kinetic energy as it is transitioning from a solid to a liquid?When a substance transitions from a solid to a liquid to a gas state, attractive forces do not become weaker; rather, the particles' increased kinetic energy, which denotes a higher rate of motion, enables them to defeat the forces.

what is the enzyme-mediated hydrolysis process that breaks down large macronutrients into smaller molecules.
Chemical digestion is the process of breakdown of large macronutrients into smaller molecules by enzyme-mediated hydrolysis.
Chemical digestion is the process by which large macronutrients are broken down into smaller molecules via enzyme-mediated hydrolysis. The hydrolysis of the C-N bond digests proteins and polypeptides. About 20% of the proteins are digested by stomach pepsin, with the remainder digested by pancreatic and small intestine enzymes.
Enzymatic hydrolysis is a process in which hydrolase-type enzymes use a water molecule to cleave a substrate into reaction products. For optimal activity, the reaction conditions (temperature, pH, etc.) are specific to each enzyme.
Hydrolases are a type of enzyme that commonly acts as a biochemical catalyst by using water to break a chemical bond, resulting in the division of a larger molecule into smaller molecules.
