Molar Mass of Al: 2(27.0g/mol) = 54.0g/mol
Molar Mass of O: 3(16.0g/mol) = 48.0g/mol
Molar Mass of compound: 102.0g.mol
(54.0g/mol / 102.0g/mol) x 100% = 52.9%
Aluminium is an element- it consists of aluminium, Al, atoms.
Aluminum. Was this supposed to be a trick question?
Aluminium is a natural chemical element and contain only aluminum atoms.
it is ch395 or the atom fact
It's an element.
Bauxite: Aluminum oxide = Al2O3
Crushing an aluminum can is a physical change because you have only changed its shape, but not its chemical composition.
Sapphire's chemical composition is aluminum oxide, Al2O3.
The answer is a paper made of moisture proof by a wax coating
The chemical properties of Steel 45C8 are carbon that is the key alloy in its composition, 0.4% silicon, 1.2% manganese and residual elements: copper, molybdenum, aluminum, chromium and nickel.
What is the chemical composition of kf reagent
That depends.
Crushing an aluminum can is a physical change because you have only changed its shape, but not its chemical composition.
Sapphire's chemical composition is aluminum oxide, Al2O3.
Many compositions are known; an example is Al8B4C7.
the percentage composition of aluminum sulfate is 342
The answer is a paper made of moisture proof by a wax coating
Yes. Physical change is when you change the appearance but not the actual object. Crushing an aluminum can is a physical change because you have only changed its shape, but not its chemical composition.
Diamond is pure carbon Also, Sapphire is Aluminum Oxide. (Analogous to how Iron Oxide is rust!)
The chemical composition of cement is Calcium oxide, Silicon dioxide, Aluminum oxide, Iron oxide, water, and sulfate. They mix, crush, and blend together limestone, silica (sand and other materials), aluminum, iron, and gypsum.
Corundum is aluminum oxide, the formula is Al2O3
The chemical properties of Steel 45C8 are carbon that is the key alloy in its composition, 0.4% silicon, 1.2% manganese and residual elements: copper, molybdenum, aluminum, chromium and nickel.
Yes, it can. Aluminum oxide, saphires or rubys are all the same mineral. Just with minor elemental differences.
