Color is most easily observed property of minerals but it is the least useful property for identification list two reasons why this is true and give one example for each?
1) The color of minerals (especially gasses) can change depending on the concentration of said mineral. The more diluted a mineral, the weaker or more washed the color will appear, which can change it's properties.
2) The color of a mineral can also be disturbed by impurities. Diamonds come in all kinds of colors because of microscopic differences within their individual constructs.
3) (just for fun) While "RED" and "BLUE" are univerally understood, "AQUAMARINE" and "CHARTRUSE" can be relative to the person, making them non-absolute.

How do scientists identify minerals?
Scientist identify minerals by Their Special properties. An example of a special propertie is a Chemical Reaction .
Why can minerals be found in rocks but rocks cannot be found in minerals?
Because rocks are made up of minerals but minerals aren't made up of rocks. Rocks are made up of little bits of many minerals. An example is granite. You know how it has speckles in it? Those are a bunch of mineral grains mixed up to form the rock granite.
With minerals what rights does an owner with 50 percent undivided interest have?
If you own an undivided one-half interest that means you own a 50% interest in the whole property. That would come into play if the mineral rights, the property, or a portion thereof was sold. For example, if the mineral rights were sold you would be legally entitled to 50% of the net profit. The buyer would be required to cut a check for that amount in your name.
Which of these minerals commonly forms as an evaporate (precipitate from evaporating water)?
For example sodium and potassium chloride are evaporites.
What are some rocks that aren't a mineral?
Rocks are not minerals. They are composed on one or more minerals. For example granite is composed primarily of the minerals quartz, potassium feldspar, and albite. There are some rocks, however, that are composed of substances that aren't minerals. Examples include coal, which is mostly organic, and glassy rocks such as obsidian, pumice, and some varieties of tuff.
How is burning an example of a chemical property?
Burning is an example of a chemical property because it can only be observed during a chemical reaction called combustion.
What is an identification test for minerals that is not generally a reliable test?
Believe it or not color is the least reliable identification method for a mineral. While it can be very helpful when used along with other types of identification tests, color alone proves nearly useless. This is because several different minerals can have the same color or one mineral can be several different colors. Generally this is due to the varying chemical compositions a single mineral can take on. For example, iron, depending on its oxidation state, can cause the same mineral to be several different colors, leaving the examiner with a large list of possibilities. Also, in another example, there are hundreds of minerals that are known to be green so again the possibilities are endless.
Is yellow gold in appearance an example of physical property?
Yes, the appearance of yellow gold is an example of a physical property because it can be observed and measured without changing the substance itself. Physical properties are characteristics that can be seen or measured without altering the composition of the material.
Properties of a substance that can be observed and measured without chemically changing the substance are considered?
Physical properties to a substance can be observed and documented without chemically changing them. Physical property examples are color, smell and size, for example.
Examines a mineral's ability to break into even pieces?
Cleavage is a minerals ability to break into even pieces useful for identification. Cleavage in two directions equals Feldspar for example.
Can some minerals be identified by their smell or size?
Yes, some minerals can be identified by their distinctive smell, such as sulfur which has a strong odor. Additionally, size can sometimes be used to determine certain minerals, for example, large crystals are often associated with minerals like quartz or calcite. However, size alone is not typically a definitive characteristic for mineral identification.
Density is an example of?
Mass, volume, and density are all example of physical properties. Physical properties are any characteristic of a substance that can be observed or measured without changing the material.
What does special proporties mean when talking about minerals?
Well, some minerals can be identified by special properties. It's practically just the kind of property a mineral has. Florescence or megnetism is an example of special properties. Hope this helped.
How do you identify the property of a mineral but what does it mean where we say calcite has a hardness?
We use Mohs scale of mineral hardness to access the hardness of minerals, which calcite is one example.
What is statement of identification?
A statement of identification would be a sentence that is used to state what something is or who someone is. For example, "I am Ashley" would be a type of identification statement.
Can the chemical properties of a substance be observed without changing the substance?
physical properties
What type of igneous rocks are easy to classify because the minerals that they contain can be seen and identified?
Rocks with large, easily identifiable minerals, such as granite and diorite, are easy to classify. These rocks belong to the intrusive igneous rock category and typically have distinct mineral compositions that allow for easy identification.
