Lavoisier organized a list of the known
elements of his day as four categories.
Newlands was the first to organize the
elements and show that properties repeated in a periodic way. Mendeleev and Meyer proposed periodic tables showing a relationship between atomic mass and elemental properties. Moseley organized the elements by atomic number instead of atomic mass.

ibuprofen, c13h18o2, is a common medicine for treating mild pain, fever, and inflammation. a concentrated stock solution of 0.02
pickupchik [31]

Answer:

26.2ml

Explanation:

This is a delusion calculation. But before performing the delusion we need to know the concentration the polarity of the original solution. The original solution was prepared by taking .021 mg of ibuprofen and dissolving it in one mil leader. So to calculate the concentration, we need to take the moles of ibuprofen, which can be calculated by taking the milligrams divided by 1000 to get grams and then divided by the molar mass to get moles and dividing the moles of ibuprofen by the leaders of the solution. One mil leader can be calculated, Can be converted into a leader by dividing by 1000. We then get a polarity of 1.018 times 10 to the negative for Mueller Than to carry out the dilution. We have a 1.018 times 10 to the negative for Mueller solution and one mil leader of it. We want to prepare 375 times 10 to the negative six molar solution. And so we need to figure out what the new total volume will be Rearranging. This equation gives us a total volume of 27.15 million l but we already have one mil leader of solution. So we need to add to that The 27.15 -1 or the 26.15 ml. The answer then of the choices available would be 26.2 ml

Two glucose solutions of different concentrations are placed next to each other but are separated by a semi permeable membrane.
sergiy2304 [10]

There are different kinds of Chemical reaction. What will occur is that a lot of water molecules will move from x to y decreasing the concentration gradient of sucrose.

  • The solution above (Image inserted) will tend to move down the concentration gradient.  That is, the water molecules will move done from the area of more water to area of less water.

Osmosis is known to be a chemical situation, where solvent molecules often water move or diffuse via a semipermeable membranes.

This is usually done in regions of low solute concentration to regions of high solute concentration until both sides are equal in concentration of solutes.  The solution is said to be water moving from a hypotonic solution to the hypertonic solution.
