Why chemical properties not always used to identify minerals?
The stripe, and color
What are the properties used to identify minerals?
luster streak shape density color (not always reliable tho mulltiple types of minerals can have the same color) odor tenacity reaction to acid cleavage magnetism electrical properties
What is the problem with using only color to identify a mineral Give an example of a mineral that demonstrates your answer?
The color of many minerals is highly variable. Many minerals are found in many different colors. Eg. while malachite is always green, and sulfur always yellow, quartz can come in shades of purple, green, blue, red, yellow, brown, pink, etc., and tourmaline, garnet, calcite, and fluorite are equally color variable.
What minerals can you identify in the specimen of gabbro?
The minerals that make up Gneiss are almost always: feldspars, quartz, and mica. Sometimes: kyanite, garnet, hornblende, tourmaline, magnetite, and many others. Source: Geology University Student

What are made up of minerals?
Well minerals is in earth inorganic solid material found in nature that always has the same chemical makeup atoms arranged in an orderly pattern and properties such as cleavage and fracture color hardness and streak and luster.
When geologists say that a mineral always contains certain elements in definite proportions they mean that the mineral always has what?
When geologists say that a mineral always contains certain elements in definite proportions, they mean that the mineral always has a specific chemical composition. This composition is a key characteristic that helps identify and classify minerals. Minerals are composed of specific elements arranged in a precise crystal lattice structure.
What does a chemical change always do?
A chemical change always changes the chemical composition of the reactants to produce products with new and unique properties, different from the reactants.
What are minerals made of?
A mineral may consist of a specific element, but is most likely a combination of elements. A mineral is an inorganic solid material found in nature that always has the same chemical makeup, atoms arranged in an orderly pattern, and properties such as cleavage, streak color, hardness and luster.
A substance always has properties even though they are difficult to observe?
Yes, all substances have inherent properties such as mass, volume, and density. These properties may not always be easily observable without specialized equipment or techniques.
What does chemical change always result in?
Chemical change always results in the formation of new substances with different chemical properties than the original substances. This can involve the rearrangement of atoms and the breaking or formation of chemical bonds.
What minerals does the rock granite always contain?
Granite always contains the minerals quartz, feldspar (potassium feldspar or plagioclase feldspar), and mica (biotite or muscovite). These minerals give granite its characteristic appearance and properties.
Are changes in properties always evidence of a chemical change and why?
Changes in properties are not always evidence of a chemical change. Physical changes, such as changes in state (solid to liquid) or appearance, can occur without any change in the chemical composition of a substance. Chemical changes involve the rearrangement of atoms and result in the formation of new substances with different properties.
Why is color not always a good way to identify minerals?
Color is not always a good way to identify minerals because some minerals change colors at certain temperatures. Some minerals have several colors and some are found in varied colors.
What does chemical weathering always form?
Chemical weathering always forms new minerals through the breakdown and alteration of pre-existing rocks due to chemical reactions with water, oxygen, or other substances in the environment.
