As of my last update, the price of one ton of mineral gypsum can vary widely depending on factors such as location, purity, and market demand, typically ranging from $30 to $100 per ton. Prices may also fluctuate based on shipping costs and regional supply conditions. For the most accurate and current pricing, it's best to consult local suppliers or market reports.

Gas prices fell below $1 per gallon in the United States during several periods, most notably in late 2008 and early 2009 due to the economic recession and a significant drop in oil prices. Additionally, some regions experienced prices under $1 during the early 1990s and in the early 2000s. These low prices are relatively rare in recent years, as gas prices have generally risen due to various economic and geopolitical factors.
The nominal GNP is the value of all the production valued at this year's prices. Real GNP is valued at prices of a base year. Thus, if an economy produces in year 1 2 oranges and 3 apples, at prices 5 and 6 respectively and in year 2, 4 oranges and 6 apples, at prices 9 and 8, then:nominal GDP year 1=2*5+3*6=28nominal GDP year 2= 4*9+6*8=84Notice that you can not compare production between two years because prices increased. It is not correct to state that production multiply by 3. So you should compute real GNP at prices of year 1Real GDP year 1 (at prices of year 1) = 28 (same as before)Real GDP year 2 (at prices of year 1) = 4*5+6*6=56
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.
The most commonly known mineral that can be scratched by a fingernail is talc.
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.
Calcite is harder than both gypsum and talc. On the Mohs scale of mineral hardness, calcite has a hardness of 3, while gypsum has a hardness of 2 and talc has a hardness of 1. This means that calcite can scratch both gypsum and talc, demonstrating its greater hardness.
Talc can scratch gypsum, but can be scratched by all other minerals. Talc is the softest mineral on the Mohs scale, with a hardness of 1, making it easily scratched by minerals with higher hardness values. Gypsum has a Mohs hardness of 2, so talc can leave a mark on it.
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.
Rocks that mostly contain minerals like mica, gypsum, and talc can be scratched by 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.
The three softest minerals on the Mohs scale of mineral hardness are talc, gypsum, and calcite. Talc, rated as the softest with a score of 1, is commonly used in talcum powder. Gypsum, with a hardness of 2, is often found in plaster and drywall. Calcite, rated at 3, is a key component of limestone and marble.
There are two basic types of mineral. 1. Macro -- It is the amount mineral needed by the body which is larger than 100 milligrams. Examples: Calcium, phosphorus and magnesium 2. Trace-- It is the amount needed by the body in small amounts Example: Iron 3.Gypsum--a common white or colorless mineral (hydrated calcium sulphate) used to make cements and plasters (especially plaster of Paris) Gypsum is a very soft mineral composed of calcium sulfate dihydrate, with the chemical formula CaSO4·2H2O. A common mineral of evaporates in inland salt playas. Calcium sulphate the raw material (minerals alabaster, satin spar, selenite) used for gypsum plasters, wallboard/drywall; gypsum plaster, unlike cement, expands on setting, does not crack unless there are faults in the backing; must never be mixed with Portland cement.
Somewhere between 3 and 5 on the Mohs scale of relative mineral hardness...
The pair that could each be composed of only one mineral is (1) dunite and rock salt. Dunite is primarily composed of the mineral olivine, while rock salt is made almost entirely of the mineral halite. The other pairs consist of rocks that are typically composed of multiple minerals.
