The mass of one mile of a compound is found by adding up the atomic masses of each of the component elements.
A mole of Al2O3 has mass of 2 × 26.98 + 3 × 16.00 = 101.96g

Al2O3 plus HBr AlBr3 plus H2O?
Al2O3 + 6HBr = 2Albr3 + 3H2O
Is hardness of MgO is greater than Alo?
i don't know whether there exists Alo,all i study so far is Al2O3both MgO and Al2O3 are ionic compouds. Al3+ is smaller than Mg2+(due to higher proton charge thus attracts the electrons closer),thus the ionic bonds in Al2O3 is greater thus it is harder.
What type of reaction is Fe2O3 plus 2Al equals 2Fe plus Al2O3?
displacement reaction............ u people have to find the answers instead asking others without shame..............
Determine the percent yield of a reaction that produces 28.65g of Fe when 50g of Fe2O3 reacts with excess Al according to the following reaction Fe2O3 plus 2Al equals Al2O3 plus 2Fe?
81.93%
What is the atomic number for Rubies?
Ruby is not a element, so it does not have an atomic number. Ruby is a red variety of the mineral called corundum (all other color varieties are called sapphires), which is composed of the elements aluminum and oxygen and has the formula Al2O3. Aluminum has the atomic number 13 while oxygen's atomic number is 8.
What compound is formed when aluminum and oxygen combine?
Aluminum oxide is formed when aluminum and oxygen combine. This compound has the chemical formula Al2O3.
What is formula for aluminum and oxygen?
The formula for aluminum oxide, which is the compound formed by aluminum and oxygen, is Al2O3.
What does 3 mean in Al2o3?
The 3 in Al2O3 represents the number of oxygen atoms bonded to each aluminum atom in the chemical formula for aluminum oxide.
What is the name of the element that is combined with alumiium in al2o3?
The element combined with aluminum in Al2O3 is oxygen.
What forms Rubies?
Al2O3, aluminum and oxygen.
In the compound Al2O3 aluminum's oxidation number is plus 3 and oxygen's oxidation number is .?
In the compound Al2O3 oxygen is oxidized to minus 2. You will note that two aluminum times plus 3 is 6, and 3 oxygen times minus 2 is minus 6; thus the combination of aluminum and oxygen yields an electrically neutral molecule, since 6 - 6 = 0.
In the compound Al2O3 aluminum has an oxidation number of 3 while oxygen's oxidation number is .?
In the compound Al2O3, aluminium has an oxidation number of +3, while oxygen's oxidation number is __-2 ____. For aluminium oxide (Al2O3) to form the ionic charges MUST balance. Hence For the 2 aluminiums it is 2 x 3 = +6 For the 3 oxygens it is 3 X -2 = -6 +6 -6 = 0 So the charges balance, hence Al2O3 is neutrally charged compound and NOT an ion.
What does al2o3 stand for?
Aluminum oxide has the molecular formula of Al2O3. It is composed of aluminum (Al) and oxygen (O) and is 102.0 grams per mole.
What happens when aluminium and oxygen combine?
When aluminum and oxygen combine, they form aluminum oxide. This process is known as oxidation. Aluminum oxide forms a thin, protective layer on the surface of the aluminum, which helps prevent further corrosion and degradation.
In the compound Al2O3 aluminum has an oxidation number of 3 while oxygen's oxidation number is?
In Al2O3, the oxidation number of aluminum is +3, as it typically loses 3 electrons to form a 3+ cation. Therefore, for the compound to be electrically neutral, the oxidation number of oxygen must be -2, as oxygen usually gains 2 electrons to reach a full octet.
To the nearest atomic mass unit what is the formula mass of aluminum oxide?
The formula mass of aluminum oxide (Al2O3) is approximately 102 atomic mass units.
