What are mine exploration samples and its purpose?
Mine exploration samples are samples of rock taken when prospeting a mine. They are used to determine how much of certain minerals of interest are present in the area.
How is science used when extracting minerals in mining?
Science is used to analyse samples from the area of interest to the mining company. It's no good mining for a specific mineral - if there's none in the target area ! Chemical analysis of the samples will determine what (if any) useful minerals are present.
What if two samples of elements each represent one mole then?
If two samples of elements each represent one mole, then they will contain the same number of atoms. This is because one mole of any substance contains Avogadro's number of particles, which is approximately 6.022 x 10^23. Therefore, both samples will have the same number of atoms, even if they are different elements.
Identify three minerals that are normally found with quartz in samples of andesite rock?
Three minerals commonly found with quartz in andesite rock are feldspar (specifically plagioclase), biotite mica, and amphibole (such as hornblende). These minerals are all typically present in andesite as part of the overall composition of the rock.
What are handlenses used for today?
I use mine to identify minerals in rock samples.
How is uranium found?
Analyzing samples of soils and waters, examinations of minerals, radiometric measurements in territory (also air surveillance).
Which samples are pure water?
Samples that are pure water include distilled water, rainwater, and water that has been filtered through a reverse osmosis system. These samples do not contain any dissolved minerals or impurities.
How can you determine if bacteria are present in your environmental samples?
To determine if bacteria are present in environmental samples, you can perform tests such as culturing the samples on agar plates, using molecular techniques like PCR, or using biochemical assays to detect specific bacterial markers.
What is a mineralogist?
A mineralogist is a scientist who studies minerals, including their composition, properties, and formations. They may analyze samples in a laboratory, conduct fieldwork to collect samples, and use various techniques to identify and classify minerals. Mineralogists play a key role in understanding the Earth's geology and mineral resources.
Is the distribution of sample means always a normal distribution If not why?
It need not be if: the number of samples is small; the elements within each sample, and the samples themselves are not selected independently.
What are mineral samples?
Mineral samples are small pieces or specimens of minerals that are collected from natural environments such as rocks or soils. These samples are typically used for identification, research, and educational purposes in geology and mineralogy. Mineral samples can come in various sizes and forms, ranging from crystals to rough fragments.
