Where does molten carbonate come from?
Sodium carbonate can be made by the Solvay process from brine (sodium chloride) and limestone (calcium carbonate). In the US there are large deposits of a mineral called Trona which is sodium bicarbonate carbonate, and it is obtained from that. Potassium carbonate is made by electrolysis of potassium chloride which is found as mineral Sylvite, which gives potassium hydroxide which is then carbonated with CO2. See wikipedia entries for Solvay Process, Trona, and Potassium Carbonate
Is sodium carbonate a renewable resource?
i have no clue i am looking for the answer too
Is sodium carbonate renewable?
Sodium carbonate is a naturally occurring mineral, but its extraction processes can impact the environment. While the compound itself is not necessarily renewable, efforts can be made to recycle and reuse sodium carbonate to reduce the need for newly mined resources.
How does calcium carbonate purify iron?
Calcium carbonate (limestone) is used in blast furnaces to capture impurities and form a slag that floats above the molten iron to keep the impurities from mixing back into the iron.
What are the properties and uses of molten wood?
Molten wood is a material created by heating wood to high temperatures until it becomes a liquid. It can be used in various applications such as 3D printing, creating bio-based materials, and as a sustainable alternative to traditional plastics. Molten wood has properties such as being biodegradable, renewable, and having good thermal insulation properties.
Is molten rock found on the surface of the earth that is called coral?
No, molten rock is not called coral. Coral is a marine organism made up of tiny, living polyps that form calcium carbonate structures, typically found in warm, shallow ocean waters. Molten rock that reaches the Earth's surface is referred to as lava, while the solidified form is known as igneous rock.
What is a skarns?
Molten rock that moves throgh crustal carbonate rock, That is heat the rock. Hot water as a form of steam or superheated fluid reats with crustal rock and other igneous material.
Are moon stone and pearl are different?
Yes. A pearl is a solid concretion of calcium carbonate produced by an oyster. Moonstone is a form of alkali feldspar, which forms from the cooling of molten rock beneath the Earth's surface.
What Made liquid by heat?
When a substance is heated, it absorbs energy in the form of heat, causing its molecules to gain kinetic energy and vibrate more rapidly. Eventually, the substance's molecular bonds weaken, allowing the particles to move more freely and rearrange into a liquid state. This process is called melting.
What can make glass?
Sand, also known as silica is the main ingredient to make glass. You also need sodium carbonate, limestone, magnesium carbonate, and additives to improve the quality and to add colors to it as well. You would take these ingredients and melt them at a temperature of 1700 degrees Celsius (3092 degrees Fahrenheit) until it is a molten liquid.
What are the 2 ways that limestone can be formed?
By cooling of molten rock under the oceans
Is dolomite renewable?
Dolomite itself is a natural rock formed over millions of years from the combination of calcium carbonate and magnesium. While it is not a limitless resource and it takes a long time for new dolomite deposits to form, it can be considered renewable on a geological timescale. However, extraction and consumption rates can outstrip the natural replenishment rate, leading to depletion of local deposits.
