An experiment was performed in lab that was supposed to produce aspirin. How could chromatography be used to tell if aspirin was actually the product of the reaction?
i would recommend using high performance liquid chromatography or the common thin layer chromatography using a spot of the sample and a spot of dissolved aspirin to compare the Rf-value or relative retention times of the 2 spots to determine if you have aspirin
What property could he easily measure in the lab to help him determine whether the metal is pure zinc?
Density. :)
How could you use a microscope to help determine whether the specimen is living or non-living thing?
wouldn't it be moving?
Why can't you use density or reactivity to determine whether a sample of cobalt or nickel?
If you had a piece of metal, you could use these properties to determine which element it is. Iron has different physical and chemical properties than the other two elements. The density of iron is much less than cobalt or nickel, and it reacts with oxygen in the air.
How could you determine the solute concentration inside a living cell?
By testing whether it is hyper or hypotonic solution. Also, the water potential!!
What properties could be used to help determine whether the sample is rreally zinc?
Melting point of the sample & Density of the sample
What properties could be used to help determine whether the sample is really gold?
melting point

How could you determine is a sample of gold is pure?
One way of determining if a sample of gold is pure, would be to compare the density with that of real gold.
How could you determine if a sample gold is pure?

How could you determine whether a bacterium fermented the following carbohydratesmannitolsorbitol adonitol or arabinose?
You could determine whether a bacterium fermented the carbohydrates, mannitol, sorbitol, adonitol, or arbinose by a color change. Also gases are formed.
What things could be used to determine whether a substance is an acid or a base?
litmus paper.
What happens if your DNA is taken?
Not sure what you mean by this question... If a sample of your DNA is taken, it can be compared to some other sample of tissue to determine if that other tissue sample came from your body. It can also be used to determine paternity/maternity, or how similar your DNA is to someone elses. It could also potentially be used to determine your genetic predisposition for certain heritable characteristics, such as various diseases or even personality traits.
Could the crime lab determine if any blood sample came from a male or female?
The blood came from shabab. thats why its black.
What could be determined if you knew the texture of an igneous rock?
You could determine whether the rock cooled underground or above the surface.
How can you determine if something is pure metal?
you will have to determine the properties of your sample, and compare these with a table of properties of metals. Density is a good easy one to start with. But you could consider colour, softness and so on.
