When 2ml of dettol is dissolved in 100ml of water the smell can be detected even on repeated dilution identify the physical nature of matter?
particles of matter are very small
Can a bottle hold hydroxide?
It depends what the hydroxide is; but common hydroxides (Sodium and Calcium hydroxides for instance) can be stored in glass bottles short-term. However, they do attack glass slowly, and equipment that is in regular contact with them can be damaged: burettes made of glass often sieze up after repeated use with these substances. Because of this slow but significant reactions, it is now more normal to see hydroxides stored in plastic bottles.
What is the difference between a compound and polymer?
polymer is compound which has repeated units and a compound may not have repeated units
What is a titration?
A titration is the use of carefully measured amounts of a known solution to determine the concentration of another. They often involve acid-base neutralisation or oxidation-reduction reactions (examples would be sodium hydroxide with hydrochloric acid, or permanganate with an iron solution). The main part of the system is the burette, a large graded tube with a controllable variable nozzle at its end. This nozzle is used to add different amounts with great precision to the solution being tested, so that an exact reading can be made - if done correctly, the titration's accuracy is limited only by the scale on the burette. A sample of the test solution (collected using a pipette with a known volume and high degree of accuracy; the sample is called an aliquot) is placed in a container, usually a conical flask, under the burette. The burette is filled with known solution, i.e. one where the concentration is know to another high degree of accuracy. The two are mixed slowly and allowed to react - for acid-base titrations an indicator will be added to the flask, for redox the solution which will change colour is put in the burette. This is continued slowly until the solution will barely react with that from the burette. At this point the amount of solution taken from the burette is recorded. Ideally, the next slightest drop of burette solution will cause a change in colour of the solution that does not change at all. If not, the new recording is made and the last step repeated. This amount is a titre. The whole experiment is repeated several times. The data is collected and averaged out. From this, an amount of known solution used, an amount of tested solutio used and eventually a concentration can be found.
What is a chain molecule made up of repeated units?
Polymer
What happens to the concentration of hydrogen ions in a 1 moles per liter solution of hydrochloric acid on repeated dilution?
The concentration become more and more lower.
Use a sentence with potency?
The potency of the medication was evident in its ability to quickly alleviate the patient's pain.

Why Tissue salts classed as vibrational medicine?
Tissue Salts may be regarded as "vibrational medicine" because of the extreme dilution of the mineral salt in the lactose or other carrier substance. For example a D6 dilution is a dilution of 1:9 repeated six times. The dilution is such that the quantity of the actual mineral salt present in the final titurated mixture can be regarded as being "in essence" only and that the effect of the medication is therefore vibrational. Personally I believe that the pathways by which tissue salts are absorbed - i.e via the membranes in the mouth and throat, is the crucial element in their effectiveness, and that the tissue salts themselves are somewhere between providing molecules of salt i.e. physical particles which are absorbed into the body, and vibrational medicine.
How is the amount of antimyocardial antibodies measured?
serum is diluted, or titered, and the test is done again. The serum is then further diluted and the test repeated until the serum is so dilute that fluorescence is no longer seen. The last dilution that showed fluorescence is the titer reported.
What is stronger 30k or 30c homeopathic?
There is no proven difference in potency between the Korsakoff and Hahnemanian method of preparation. Because the Korsakoff method uses the same vial for repeated dilution and succussion stages, it may be theorized to contain multiple potencies from 1-30k.
Order these decimals from least to greatest 0.25 0.25 repeated 0.225 repeated 0.255 repeated?
0.225 Repeated, 0.225, 0.25 Repeated and 0.25.
What are diagnostic signs if inattention?
Difficulty in maintaining concentration on a task, failure to follow instructions, difficulty in organizing approaches to tasks, repeated misplacement of tools necessary for tasks, and tendency to become easily distracted.

What is a sentence for the word repeated?
When the answer was repeated, she understood it better.
What does repeated mean in math?
Division. Multiplication is repeated addition.
What is repeated multipliction?
Repeated multiplication is called raising to a power.
