To determine the types of minerals in a rock, I would perform a hardness test using the Mohs scale to assess scratch resistance. A streak test would reveal the color of the mineral's powder, helping to identify it. Lastly, I would conduct an acid test, applying a dilute hydrochloric acid solution to observe any reaction, which can indicate the presence of carbonates.
Pure materials, especially minerals, are measured on a hardness scale. There are three basic tests: indentation hardness, scratch hardness and rebound hardness. See Wikipedia
Three important minerals for life are calcium, sodium, and magnesium.
You could perform a scratch test by trying to scratch one mineral with another. Whichever mineral leaves a mark or scratch on the other is harder. By comparing the results of scratching each mineral with the others, you can determine their relative hardness.
Three visible properties of minerals are color, luster (appearance of the surface in light), and crystal shape or habit.
It isn't clear what you want to determine about the star.
i dont know i dont even know how i got on this

To determine if a sentence is complete, you can use three tests: first, check if it contains a subject and a verb; second, ensure it expresses a complete thought without leaving the reader hanging; and third, verify that it adheres to grammatical rules, including proper punctuation. If a sentence meets all these criteria, it can be considered complete.

There are three main symptoms that occur when esophageal function is abnormal: difficulty with swallowing (dysphagia), heartburn, and chest pain. Doctors perform a variety of tests.
Ice, Ore and Tin are examples of three lettered minerals.
Assuming all three show no signs of life, you will only be able to perform CPR on one person. You will need to take a class that includes triage as a subject to determine which is the best candidate. Even with triage training, sometimes it is a judgment call to determine who you would perform CPR on.
The three minerals that are metals and can scratch glass are iron pyrite (pyrite), hematite, and magnetite. These minerals have a high hardness level, allowing them to scratch glass and show metallic luster.

The three micronutrients are vitamins, minerals, and water.
