Is BN a compound or element?
BN is the compound boron nitride. It can be used as a lubricant like graphite or as an abrasive like diamonds depending on the crystal form and when very pure has semiconductor properties like silicon, germanium, aluminum phosphide, and gallium arsenide.
Is aluminum oxide an amphoteric oxide?
Aluminum*)oxide is an amphoteric compound by being both 1. acidic and 2. alkaline1. acidicIt will dissolve in hydroxide (an alkaline solution):Al2O3 + 2OH- + 3H2O --> 2 Al(OH)4- aluminate anion2. alkalineIt will dissolve in acidic H+ solution:Al2O3 + 6H+ --> 2Al3+ + 3H2OThe amphoteric, neutral formula can be written as both Al2O3.(H2O)3 and: 2Al(OH)3Added(The same answer, but this time written without ions in solvent):Aluminium*)oxide is amphoteric:Al2O3(s) can react with a base:Al2O3(s) + 2NaOH(aq) + H2O(l) --> 2NaAl(OH)4(aq)Aluminium oxide + sodium hydroxide + water --> sodium aluminateAl2O3 can react with an acid:Al2O3(s) + 6HCl(aq) --> 2AlCl3(aq) + 3H2O(l)Aluminium oxide + hydrochloric acid --> aluminum chloride + water*) The USA spells Al as aluminum; British Isles as aluminum. Both are correct.
Is Barium oxide acidic or basic oxide?
Aluminium oxide is an amphoteric substance, meaning it can react with both acids and bases, such as hydrochloric acid and sodium hydroxide, acting as an acid with a base and a base with an acid, neutralising the other and producing a salt.
What are examples of amphoteric oxides?
From the USDOT Pipeline and Hazardous Materials Safety Administration Glossary: A metal that is susceptible to corrosion in both acid and alkaline environments. Aluminum is an example of an amphoteric metal.
Classification of oxides?
Oxides are classified into 3 types: > Basic oxide > Acidic oxide > Amphoteric oxide (both Basic and Acidic)
What gem mineral is an oxide of aluminum?
Ruby and sapphire are both gem varieties of the mineral corundum, an aluminum oxide.
Is aluminum made of molecules or atoms?
both, on the outside it's aluminum oxide but the inside is just aluminum
Is BN a compound or element?
BN is the compound boron nitride. It can be used as a lubricant like graphite or as an abrasive like diamonds depending on the crystal form and when very pure has semiconductor properties like silicon, germanium, aluminum phosphide, and gallium arsenide.
Does ammonia react with aluminum oxide?
Yes ammonia can react with aluminum oxide. Aluminum oxide is ampoteric, that is, it shows both acidic and basic characters. Ammonia is basic in nature, so there will be a reaction between acidic and basic chemicals.
Is aluminum oxide a base?
It is amphoteric, meaning that it is both an acid and a base in different situations.
What means that it can act as an acid or base?
These are called amphoteric. They can react and neutralise both acids and alkalis. Such examples include aluminum oxide, zinc oxide and beryllium oxide.
What elements would you expect exhibit properties most similar to those of aluminum?
The elements immediately above and below aluminum in the same column of a wide form periodic table: boron and gallium. As is usual for relatively light elements, aluminum is more like the element below it, gallium, than the one above it: Aluminum and gallium are both metals, while boron is a nonmetal. In compounds with oxyanions, however, boron is similar to aluminum compounds with oxyanions.
Is an aluminum can a compound element heterogeneous or homogeneous mixture?
Aluminum cans are made almost entirely of aluminum. The interiors are made of aluminum oxide, which is highly resistant to corrosion. This is a compound, not a mixture.
Why is silicon considered to be the material of choice in ics?
easy to process.good maximum junction temperature rating. (150C)both oxide & nitride are insoluble solids and good insulators.reasonably high speed.etc.Carbon as diamond would have better junction temperature rating. (600C) but is too brittle to process and oxide is a gas.Gallium Arsenide is faster but harder to process.Germanium is easier to process but both oxide & nitride are water soluble and junction temperature rating is low. (60C)etc.
What oxides behave as both acids and bases?
Yes, it can. When an oxide behaves as acid and base, it is neutral. Examples: Aluminum oxide and the most common: water
