Can Chemical evaluation can be done by testing the mixture as a whole?
Chemical evaluation of a mixture can be done collectively by testing the mixture as a whole. However, for a more detailed analysis, it may be necessary to conduct individual tests on the components within the mixture to determine their specific chemical properties and concentrations.
Can you tell if a mixture is a mechanical mixture by looking at it?
You can recognize a mechanical mixture because it consists of different substances that you can see and separate out of it. Examples of mechanical mixtures are cereal and milk in a bowl, soil that contains small pebbles, twigs, and bits of leaves.
Biochemical tests are used to determine what?
Biochemical tests are used to determine the presence of specific molecules, such as proteins, enzymes, or metabolites, in a sample. These tests help to diagnose diseases, monitor treatment, and assess overall health status based on the chemical reactions happening in the body.
What are identification tests of phenol?
You add a specific ionic compound in a solution to determine if phenol or any of its derivatives are present. Ferric chloride (FeCl3) for example, can be used for such tests. Basically, when you mix the solution with the compound, the ions will interact with the phenol molecules or groups, and as a result, the solution will briefly change color. If there is no colour change in the solution, this suggest there is no phenol or phenol-based molecules in your solution.
Are lipid tests done to fetuses?
Lipid tests are performed on amniotic fluid to determine the maturity of the fetal lungs.
When copper sulphat is stirred into a water water turns blue what two tests carry out to see whether this mixture is suspension or a solution?
A suspension is cloudy or will not allow light through, a solution is clear even though it can be colored. One way to test is to shine a light through the water mixture and see if it allows light to come through without breaking it up or dimming it. If it does it's a solution, if not its a suspension.

How can you tell if a green powder is a compound or mixture?
A green powder is likely a mixture if it is composed of different substances that can be physically separated. If the powder has a uniform composition and cannot be separated into different components by physical means, it is likely a compound. Chemical analysis and tests can also help determine if the green powder is a compound or mixture.
Do pregnancy tests work on cats to determine if they are expecting kittens?
No, pregnancy tests for humans do not work on cats. Veterinarians can determine if a cat is pregnant through physical exams, ultrasounds, or blood tests.
What is the sugar Benedict's solution tests for?
glycerol (sugar)
What types of tests are compared data from an experiment to determine if results are due to chance?
statistical tests
What is the function of the tests?
Kidney function tests help to determine if the kidneys are performing their tasks adequately.
What is an example of a test a chemist might do?
A chemist might conduct a titration test to determine the concentration of a solution by reacting it with a solution of known concentration. This allows them to calculate the amount of substance present in the sample.
How do scientists determine safety in cars?
Crash tests.
