A collector of minerals would want a sample of?
salt
Is it true or false that characteristic properties of elements do not depend on the amount of material present in a sample of the element?
It is true.
What characteristic depends on the amount of matter in the sample This is based on the Classification of Matter Worksheet.?
extensive property, my dear Watson.
What is a property of matter that is always the same no matter what size the sample?
yooh mom :] :] :?] >:?] :] :=] :"] :] >:] :] :]
What is the composition of Graphite Schist?
Graphite schist is mainly composed of graphite, but can also contain other minerals, such as pyrite, depending on the sample
Is a sample a number describing some characteristic of a statistic?
No. A statistic is a number describing a characteristic of a sample.
Which information would probably be most helpful to someone trying to identify a mineral sample?
Many igneous rocks can be identified by the position of their minerals.
Is a parameter a measurable characteristic of a sample?
this is false... a parameter is a measure of a mean or mode, a measurable characteristic of a sample is called a statistic.
Compare and contrast the different simple tests for mineral identification presented in the lesson?
There are several different tests that can help identify minerals. You can use any of them to determine the sample.
Why may a geologist have to break a mineral sample to determine its true color?
Rocks are exposed to the elements and undergo weathering. This can cause the minerals that they are composed of and that are exposed at the surface to become discoloured which can make them hard to identify. A geologist will often use a geological hammer to crack the rock sample to see the fresh, unweathered minerals.
What is a flame tested used for?
To identify an unknown sample by its emission spectrum
What is a charateristic poperty?
A characteristic property is a chemical or physical property that helps identify and classify substances. The characteristic properties of a substance are always the same whether the sample you are observing is large or small. Examples of characteristic properties include freezing/melting point, boiling/condensing point, density, magnetism, and solubility.
What sample size is sufficient for stat?
A sample size of one is sufficient to enable you to calculate a statistic.The sample size required for a "good" statistical estimate will depend on the variability of the characteristic being studied as well as the accuracy required in the result. A rare characteristic will require a large sample. A high degree of accuracy will also require a large sample.
Do characteristic properties change when sample changes?
No they do not change
Can luster change from sample to sample of the same mineral?
is luster a phsical property of minerals
What are the considerations for the choice of sample size?
Some considerations are:large samples take more time and money to processif the characteristic of interest is very variable then a large sample is required for accurate estimatesif the characteristic of interest is very rare in the population then a large sample is required to ensure that units with that characteristic are included in the samplethe greater the accuracy required of the estimates based on the sample, the larger the sample required.
How many restriction enzymes are needed to positively identify a sample of DNA?
10-12 different restriction enzymes to positively identify a sample of DNA.
