What mineral is harder than gypsum but softer than flourite?
Calcite is a mineral that is harder than gypsum but softer than fluorite on the Mohs scale of mineral hardness. Calcite has a hardness of 3, while gypsum has a hardness of 2 and fluorite has a hardness of 4.
What mineral contains oxygen and carbon is softer than fluorite but harder than gypsum and effervesces when it contact acid?
The mineral you are describing is calcite. Calcite contains both oxygen and carbon, and it has a hardness of 3 on the Mohs scale, making it softer than fluorite (hardness of 4) but harder than gypsum (hardness of 2). Additionally, calcite is known for its characteristic effervescence when it comes into contact with dilute acid, due to the release of carbon dioxide gas.
What minerals are softer than gold?
Minerals that are softer than gold include talc, gypsum, and calcite. These minerals have a lower hardness level on the Mohs scale compared to gold, which has a hardness of about 2.5 to 3.
Which mineral would halite be able to scratch?
Halite, which has a Mohs hardness of 2.5, can scratch minerals that are softer than it on the hardness scale. This means it can scratch talc (hardness 1) and gypsum (hardness 2). However, it would not be able to scratch minerals like calcite (hardness 3) or any harder minerals.
What is softer than quarts but harder than apatite?
Topaz is softer than quartz but harder than apatite on the Mohs scale of mineral hardness. It has a hardness of 8 on the scale, whereas quartz has a hardness of 7 and apatite has a hardness of 5.
What mineral is harder than gypsum but softer than flourite?
Calcite is a mineral that is harder than gypsum but softer than fluorite on the Mohs scale of mineral hardness. Calcite has a hardness of 3, while gypsum has a hardness of 2 and fluorite has a hardness of 4.
Which two minerals are softer than a human fingernail?
Talc and gypsum are two minerals that are softer than a human fingernail, which has a hardness of about 2.5 on the Mohs scale. Talc has a hardness of 1, while gypsum has a hardness of 2.
What minerals are softer than gold?
Minerals that are softer than gold include talc, gypsum, and calcite. These minerals have a lower hardness level on the Mohs scale compared to gold, which has a hardness of about 2.5 to 3.
A human fingernail has a hardness of approximately 2.5 Which two minerals are softer than a human fingernail?
Talc and gypsum are two minerals that are softer than a human fingernail. Talc has a hardness of 1 on the Mohs scale, while gypsum has a hardness of 2.
Does gypsum scratch flourite?
No. Gypsum has a hardness on the Mohs scale of 2. Topaz has a hardness on the Mohs scale of 8. This means that topaz ranks much harder than gypsum and that gypsum cannot scratch topaz. Please do not refer to these numbers as absolute hardness. This does not mean that topaz is 4 times as hard as gypsum since they are ranked 8 and 2. The Mohs scale only designates a hardness scale of 1 through 10 so that geologists and mineralogists in the field have a quick way of determining a mineral's identity or eliminating possible options of what the mineral may be.
Which mineral would halite be able to scratch?
Halite, which has a Mohs hardness of 2.5, can scratch minerals that are softer than it on the hardness scale. This means it can scratch talc (hardness 1) and gypsum (hardness 2). However, it would not be able to scratch minerals like calcite (hardness 3) or any harder minerals.
What is softer than quarts but harder than apatite?
Topaz is softer than quartz but harder than apatite on the Mohs scale of mineral hardness. It has a hardness of 8 on the scale, whereas quartz has a hardness of 7 and apatite has a hardness of 5.
Contains oygen and carbon softer than fluorit but harder than gypsum?
limestone
What is the hardness of a mineral that scratches gypsum?
The mineral that scratches gypsum has a hardness greater than 2 on the Mohs scale. Gypsum has a hardness of 2 on the Mohs scale, so any mineral that can scratch it must have a hardness greater than 2.
Hardness of sodium chloride crystal in moh's scale?
Sodium chloride (table salt) has a hardness of 2-2.5 on the Mohs scale. This scale measures the scratch resistance of various minerals through the ability of a harder material to scratch a softer one. As a result, sodium chloride can be easily scratched by materials with a higher hardness, such as gypsum (hardness 2) and calcite (hardness 3).
How hard is brick on moh's hardness scale?
Brick falls within the range of 5-7 on the Mohs hardness scale, depending on its composition and firing process. This means that brick is harder than materials like fingernails and gypsum, but softer than materials like steel and glass.
Contains oxygen and carbon softer than fluorite but harder than gypsum fizzes quickly?
The mineral being described is likely calcite. Calcite is composed of oxygen and carbon, has a hardness between fluorite and gypsum, and fizzes quickly when in contact with acid due to its reaction to the acid's carbonate content.
