What test and experimental results indicate that acetone has been separated from water?
One common test to confirm the separation of acetone and water is to measure the boiling points of the two substances. Acetone has a lower boiling point than water, so when the mixture is heated, acetone evaporates first. To confirm the separation, distillation can be used to collect the evaporated acetone and leave behind the water. This process can be repeated to ensure complete separation.

What indication do the experimental results give regarding the purity of the samples used?
The experimental results can provide information on the presence of impurities in the samples. Deviations from expected results or unexpected peaks in analysis can indicate the presence of impurities affecting the purity of the samples. Further analysis or repeated experiments may be necessary to confirm the purity of the samples.
What is the reaction of polystyrene and acetone?
When polystyrene (a plastic) is in contact with acetone, it can dissolve or soften the polystyrene. This is because acetone is a solvent that can break the bonds within the polystyrene polymer, causing it to swell or dissolve.
Why acetone free absolute alchohol is used in leishman stain?
Acetone-free absolute alcohol is used in Leishman stain to prevent the denaturation of cellular components and ensure better stain retention. Acetone can cause precipitation of proteins and alter the staining results, whereas acetone-free alcohol provides a more stable environment for staining.
In an experiments what happens to the control group?
The control group serves as a baseline for comparison with the experimental group. It does not receive the experimental treatment or intervention, allowing researchers to measure the effect of the treatment by comparing the results of the control group to those of the experimental group.
Why do mixtures of acetone and chloroform exhibit significant negative deviations from Raoult's law?
Mixtures of acetone and chloroform exhibit negative deviations from Raoult's law because the molecules of acetone and chloroform have different intermolecular interactions. Acetone forms stronger intermolecular interactions with chloroform than with itself, leading to a decrease in vapor pressure and lower than expected boiling point. This results in the formation of more stable mixed solvent molecules, causing negative deviations from Raoult's law.
Which is one way scientist indicate how precise and accurate their experimental measurements are?
Scientists indicate the precision and accuracy of their experimental measurements by reporting the uncertainty associated with their data. This can be done by calculating and expressing the range or margin of error in the results. Additionally, scientists may repeat measurements multiple times to assess consistency and variability in the data, which helps determine the reliability of the results.
Can you fail a Breathalyzer if you have diabetes?
In diabetes there is improper metabolism that results in acetone. Acetone can confuse the Breathalyzer, since it give results as ethanol (alcohol).

What is a sentence for experimental?
We are currently in the experimental stage.They have a very experimental love live.These experimental conditions are not good enough.
Why was Robert Andrew supprised by his experimental results?
there was no answer
What is numbers which are the results of an experiment?
These are the experimental values.
How are experimental results analyze?
by using data
What is the proposed explanation for observations and experimental results?
theory
What is a summary of experimental results and observations called?
Law
What is a summary of many experimental results and observations?
Law
What is the importance of theoretical and experimental research in physics?
Theoretical results obtained give an approximate range of the experimental results. This indicates the issues that occur before implementing it experimentally.
Why is experimental control needed in experiments?
The experimental control is what you compare your experimental data with. Without the control, you can't tell if the variable you are testing is what is causing your results.
