Is balsa core a good core material?
The answer depends on what you intend to build. Balsa is a very lightweight but flimsy material that is good for building model airplanes, among other things, but may not be useful if you intend on using it for any type of load-bearing.
What types of solutions may be obtained if the amount of ingredients is changed?
The new solutions obtained have other concentrations for solutes.
Where can nitrogen be found or mined at?
Elemental Nitrogen may be conveniently obtained by cryogenic distillation from the atmosphere. The liquid form is widely used as a low temperature coolant. It is an important part of our diet, and is found in proteins. Nitrates are very useful chemicals, and until recently, were obtained from immense deposits of seabird droppings, sometimes called guano.
Why do we produce alloys?
alloys (which are a mixture of 2 or more metals) are made because it produces a new material which is stronger/more resistant to heat/more rigid/more easily manipulable and so make the resultant material more usable a common example is steel which is a mixture of iron (which when left exposed to the elements may rust) and carbon. The result is a very strong material which will not rust and is therefor more useful
Why might a useful chemical be dangerous?
Because a useful chemical may be corrosive or toxic, radioactive or inflammable, explosive or carcinogenic etc.
What useful material may be obtained from bauxite what useful material may be obtained from hematite what are bauxite and hematite called since they produce useful material?
Bauxite is aluminum ore, hematite is iron ore.
What useful material may be obtained from bauxite what useful material may be obtained from hematite what are bauxite and hematite called since they produce useful materials?
Bauxite used to produce aluminium. Hematite can be used to produce iron. Bauxite nd hematite are called minerals and in the context of metal production ores.
What useful material may be obtained from bauxite and hematite?
Bauxite is the primary raw material for production of aluminum and hematite is the primary raw material for production of iron. Materials such as bauxite and hematite that are naturally occurring sources for metals are called "ores".
What materials may be obtained from bauxite?
Removal of iron from aluminous material such as bauxite is effected by treatment with a gas mixture comprising sulphur dioxide and carbon monoxide in a first step, followed by chlorination in a second step whereby ferric chloride is produced and removed by volatilization.
Is bauxite a substance?
Bauxite is a sedimentary rock that is the main ore of aluminum. Bauxite varies in composition, as does any rock, but the main components are minerals of aluminum oxide and aluminum hydroxide. Bauxite may also contain amounts of iron, clay, silt and silica. Bauxite is the result of the leaching of minerals from tropical soils leaving a hardened clay-like material that is high in the above minerals, which resist leaching. In addition to being the primary source of aluminum, some bauxite is also used in the manufacture of abrasives.
When would it be useful to estimate?
An estimate, which can be obtained quickly, can sometimes be sufficient for the immediate purpose. It may be better than an exact answer which will take time.
Bauxite is considered an ore because?
Because of it's hardness!2. Bauxite is considered an Ore because it may be used as a source of metal (aluminum).
How is aluminuim made?
Raw MaterialsAluminum compounds occur in all types of clay, but the ore that is most useful for producing pure aluminum is bauxite. Bauxite consists of 45-60% aluminum oxide, along with various impurities such as sand, iron, and other metals. Although some bauxite deposits are hard rock, most consist of relatively soft dirt that is easily dug from open-pit mines. Australia produces more than one-third of the world's supply of bauxite. It takes about 4 lb (2 kg) of bauxite to produce 1 lb (0.5 kg) of aluminum metal. Caustic soda (sodium hydroxide) is used to dissolve the aluminum compounds found in the bauxite, separating them from the impurities. Depending on the composition of the bauxite ore, relatively small amounts of other chemicals may be used in the extraction
What is mind out bauxite land?
Bauxite is a mineral rich in aluminum ore. However, the phrase "mind out bauxite land" means nothing whatsoever and is in fact gibberish. Even if you were to substitute the homonym "mined" for "mind" it still wouldn't be a coherent phrase, although one might suspect that we may be talking about exhausted bauxite mines here.
What is the raw materials of Aluminum?
Aluminium is extracted from an ore called bauxite. In can be used as a raw material though, such as when alloys are made with aluminum additions. Aluminium is not found natuarally as aluminum.
What has the author Mary Josephine Booth written?

What does forms may be obtained from?
