What else can I help you with?
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.
If an iron nail is harder than gypsum and softer than calciteapproximately what hardness might it rate?
An iron nail typically has a hardness of around 4 to 5 on the Mohs scale. Gypsum rates at about 2, while calcite is around 3. Therefore, since the iron nail is harder than gypsum and softer than calcite, it would likely rate closer to 4.
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.
Compare the hardness of gypsum to an everyday substance?
Gypsum has a hardness of 2 on the Mohs scale, which means it can be easily scratched by substances like a fingernail. In comparison, talc, which is the softest mineral, has a hardness of 1, while gypsum is much softer than common materials like chalk or soapstone. This makes gypsum a relatively soft mineral, easily identifiable by its ability to be scratched with minimal force.
Which mineral is softer then steel file but harder than glass?
The mineral that is softer than a steel file but harder than glass is typically quartz. Quartz has a hardness of about 7 on the Mohs scale, while glass usually ranges around 5.5, and steel files can be harder, often rated around 6.5 to 7.5 depending on the specific type of steel. Therefore, quartz fits the criteria of being softer than a steel file but harder than glass.
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.
What is a mineral that contains oxygen and carbon softer than fluorite but harder than gypsum and effervesces when it contacts an acid?
Calcite (CaCO3).
What kind of mineral will scratch a mineral?
A harder mineral will scratch a softer one.
Contains oygen and carbon softer than fluorit but harder than gypsum?
limestone

Is the following question true or false a mineral can scratch any mineral harder than itself?
True. In general, a mineral can scratch any mineral that is softer than itself according to Mohs Scale of Mineral Hardness. This means that a mineral with a higher number on the scale can scratch a mineral with a lower number.
What kind of test is it when you scratch a mineral with a nail?
Most likely you would be testing to see if the mineral was harder or softer than the nail.
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.
Which mineral is softer than a fingernail?
On the Mohs hardness scale, Stibnite is about 2 while fingernails are about 2.2-2.5. This means that stibnite is softer than a fingernail, but only slightly.
Can Gypsum can scratch diamond?
No, gypsum cannot scratch diamond. Diamond is the hardest mineral on the Mohs scale with a rating of 10, while gypsum is much softer with a rating of 2, which means diamond is able to scratch gypsum but not the other way around.
