How is the viscosity of asphalt cement affected by temperature?
At high temperatures, the asphalt will become less viscous and more like a free-flowing liquid. At low temperatures, it will solidify.
How does temperature and salinity effect the stability of water?
The chemical stability of water is not affected by the salinity; also water decompose at very high temperatures.
Nuclear fusion requires extremely high?
Nuclear fusion requires extremely high temperatures, and pressures.Nuclear fusion requires extremely high temperatures, and pressures.Nuclear fusion requires extremely high temperatures, and pressures.Nuclear fusion requires extremely high temperatures, and pressures.
What does galena react with?
Galena is lead (II) sulfide. It's fairly non-reactive, though at high enough temperatures it will react with atmospheric oxygen to form lead (II) oxide and sulfur dioxide.
Is the enzymes affected temporarily or permanents?
That depends on the physical conditions. High temperatures, some substances or changes in pH cause enzymes to be permanently denatured. Very low temperatures and the presence of some inhibitors cause enzymes to be temporarily unable to catalyse reactions.
In fizzy drinks should carbon di oxide be added at low or high temperature?
high temperatures
What are nitrogen oxide emissions and how do they affect the environment?
Nitrogen oxide emissions are the product of fuel burning at high temperatures. It affects the environment by contributing to acid rain.
What would you see if you heated copper oxide with powdered iron?
Thermite is a high-temperature incendiary composition that can successfully reach temperatures of 2500 degrees Celsius. A thermite reaction--sometimes called a "Goldschmidt reaction"--refers to the very exothermic process occurring between a metal oxide such as Iron (III) oxide, Manganese (IV) oxide, or Copper (II) oxide, and a more reactive pure metal, such as Magnesium or Aluminium. The more reactive pure metal reduces the metal Oxide, Oxidizing itself and releasing a substantial amount of energy during the reaction. Usually the mixture is made by simply combining the ingredients, and then igniting it, which takes very high temperatures. The reaction releases so much energy, molten metal is produced as one of the products. This can often times become airborne when the reaction is sufficiently energetic, and poses major health hazards.
Is ethylene oxide flammable non flammable or support combustion?
ETO is a flammable gas. At high temperatures it will burn with no outside oxygen.
What mechanical properties of a weld in carbon manganese steel is most affected if the heat input per unit length of weld is excessively high?
Toughness
How is the viscosity of asphalt cement affected by temperature?
At high temperatures, the asphalt will become less viscous and more like a free-flowing liquid. At low temperatures, it will solidify.
Magnesium oxide as a refractory lining material?
Magnesium oxide is used to make linings for some furnaces. It is known as a refractory material - which just means that it is resistant to heat.Magnesium oxide has a high melting point (2852°C) and so resists the high temperatures in a furnace. Its melting point is high because of the strong ionic bonds between the small Mg2+ and O2- ions.
What role does iron oxide play in the Haber process?
the role it plays is by using an iron oxide catalyst eliminates the need for excessively high temperatures and without the catalyst the production of significant amounts of ammonia is too slow to be economical
Which type of reaction is the heating of magnesium oxide?
If heated to a high enough temperature it would be a decomposition reactions. Under normal temperatures (say under 5000 degrees F), nothing will happen. There will be no reaction. Above such high temperatures it will decompose to Mg^2+ and O^2-
How does temperature and salinity effect the stability of water?
The chemical stability of water is not affected by the salinity; also water decompose at very high temperatures.
What are the various grades of magnesium oxide?
Magnesium oxide is categorized as a refractory material, which means that it is resistant to decomposition by heat, pressure or chemical attack and retains strength and form at higher temperatures.Rahul Magnesia Pvt. Ltd. is one of the leading manufacturer and supplier of magnesium oxide from India. The company also deals with exports of calcined magnesium oxide, magnesium sulphate, magnesium chloride, magnesium carbonate and light magnesium oxide.Light Burned Magnesium OxideLight burned magnesium oxide is a reactive grade of magnesium oxide that has been calcined at temperatures ranging from 700ºC – 1000ºC. Rahul Mag’s high purity light burned magnesium oxide products have a wide range of reactivity and are used in various applications.Hard burned Magnesium OxideHard burned magnesium oxide is a low reactive grade of magnesium oxide that has been calcined at temperatures ranging from 1000ºC – 1500ºC. Due to its narrow range of reactivity, hard burned magnesium oxide is typically used in applications where slow degradation or chemical reactivity is required.Dead Burned MgODead burned magnesium oxide has been calcined at temperatures ranging from 1500ºC – 2000ºC in a high temperature shaft kiln yielding a material with very little reactivity. Dead Burned Magnesium Oxide products are high purity, dead burned magnesium oxides with high density and low reactivity.Specialty MgOSpecialty magnesium oxides are manufactured to precise specifications in chemistry, size and surface area. Specialty high surface area magnesium oxides are calcined at temperatures below 700°C to produce highly reactive magnesium oxides for use in specialty applications.
How does manganese interact with other nutrients?
High doses of manganese may inhibit the absorption of iron, copper, and zinc. Alternatively, high intakes of magnesium, calcium, phosphorus, iron, copper, and zinc may inhibit the absorption of manganese.
