If 0.70 mol of aluminum combines with 0.250 mol of chloride, what is the empirical formula of the aluminum chloride?This is what have:Al 0.70/26.980.0259Cl0.250/35.4530.00710.0259/0.00713.65The answer my teacher gave is Al3ClCan someone please explain? I'm not sure what I am doing is right!Thanks!!! :)
Aluminium would not corrode, in factor of incontrovertible fact that it age hardens over an prolonged quantity of time and finally can grow to be extra brittleMany applications for using aluminium contain yet another sort of fabric to make it better reckoning on the ingredient being syntheticthe integration of two or extra components mutually is stated as an alloy.
Aluminium is protected by a thin layer of extremely insoluble aluminium oxideWith iron, the iron oxide (rust) tends to lift off, revealing fresh iron underneath, which therefore keeps on rusting.
Aluminium does corrode, resulting in the formation of an aluminium oxide layer on its surfaceThe aluminium oxide layer is impermeable to moisture and air, so no further reaction occursIron oxides and hydroxides however, are permeable to air and moisture, so corrosion can keep going through the metal, until all is oxidisedOn a related note, zinc is used to protect other metals (galvanising)Zinc reacts with oxygen to form zinc oxide, which reacts with CO2 in the air to form zinc carbonate, which is another impermeable layer that protects the rest of the metal from corrosion.
In spite of the fact that aluminum is chemically very active, it does not corrode in moist air the way iron doesInstead, it quickly forms a thin, hard coating of aluminum oxideUnlike iron oxide or rust, which flakes off, the aluminum oxide sticks tightly to the metal and protects it from further oxidationThe oxide coating is so thin that it is transparent, so the aluminum retains its silvery metallic appearanceSea water, however, will corrode aluminum unless it has been given an unusually thick coating of oxide by the anodizing process.
You don't need any atomic or molar masses - the given information is already in molesDivide by the smaller number of moles: (0.70 mol Al) / 0.250 2.80 (0.250 mol Cl) / 0.250 1.00 Round to the nearest whole numbers to find the empirical formula: Al3Cl [This is chemical nonsense, but that's what the given information says.]
