What are the mineral chemical compositions of the rock samples collected from the excavation site?
The mineral chemical compositions of the rock samples collected from the excavation site include elements such as silicon, oxygen, aluminum, iron, calcium, sodium, and potassium.
What mineral fizzes when it it comes in contact with hydrochloric acid?
Calcite mineral fizzes when it comes in contact with hydrochloric acid due to the reaction that produces carbon dioxide gas. This fizzing can be used as a simple test to identify calcite in geological samples.
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.
Are all samples of water have the same composition of hydrogen and oxygen?
Yes, all samples of water have the same composition of hydrogen and oxygen, with each water molecule containing two hydrogen atoms and one oxygen atom. This is consistent regardless of the source or location of the water.
Weight of 1000 identical samples of a substance is 10 pounds what is the weight of 10 samples?
The weight of each sample would be 0.01 pounds (10 pounds / 1000 samples). Therefore, the weight of 10 samples would be 0.1 pounds (0.01 pounds x 10 samples).
Is the cleavage for a mineral is always the same for that mineral?
Yes, all different samples of that mineral will have the same cleavage.
Is the cleavage for a mineral always the same for that mineral?
Yes, all different samples of that mineral will have the same cleavage.
Why do samples dissolve in mineral oil but not water?
I don't know what these samples are of, but somethings just dissolve in oil but not in water. That's one of the properties they have.
What are the mineral chemical compositions of the rock samples collected from the excavation site?
The mineral chemical compositions of the rock samples collected from the excavation site include elements such as silicon, oxygen, aluminum, iron, calcium, sodium, and potassium.
Who discovered the mineral moissanite?
The mineral moissanite was discovered in Canyon Diablo in 1983 by Henri Moissan. Moissan discovered the mineral while examining rock samples from a meteor crater.
Suppose you have two mineral samples with the same hardness What other mineral properties could you use to decide whether the two samples are the same mineral?
You could use properties such as cleavage, streak color, color, density, luster, and crystal habit to differentiate between the two samples. These properties can help determine if the samples are the same mineral or different minerals, even if they have the same hardness.
How is the mineral content of the body measured?
The mineral content of the body may be measured by testing samples of blood plasma, red blood cells, or urine.
What mineral can be found in all samples of rhyolite and andesite?
Quartz is the mineral that can be found in all samples of rhyolite and andesite. Both of these volcanic rocks are intermediate to felsic in composition, and quartz is a common constituent of such rocks. Its presence is a key characteristic that helps distinguish these types of volcanic materials.
How can you find rocks for sciences?
Learning supply houses such as Wards will sell you many rock and mineral samples for use in study. State Geological Survey departments will often send samples to educators for no fee.
You can roughly compare the of two mineral samples of the same size by hefting them?
Hefting is a simple method to roughly compare the weight of two mineral samples. By holding them in each hand, you can estimate which one is heavier based on the weight you feel. Keep in mind that this method is subjective and can only provide a general comparison, not precise measurements.
Where can you find or buy small samples of sandstone limestone chalk and shale for testing?
You can try contacting geological supply companies, universities with geology departments, or online vendors specializing in rock and mineral specimens to purchase small samples of sandstone, limestone, chalk, and shale for testing. You may also consider visiting mineral shows or rock shops that sell geological specimens.
How can porcelain tile be used to idintify a mineral?
Mineral samples can be scraped across the bottom (i.e., the unglazed side) of a tile to create a colour streak which is characteristic of the mineral. Note that it takes more than a colour streak to identify a mineral. Many minerals have the same colour streak. Other characteristics such as the hardness and density will also need to be determined in order to positively identify a mineral.
