If aluminum and calcium were to combine, the resulting compound would likely be a binary ionic compound with the formula Al2Ca3. This compound would consist of aluminum ions (Al3+) and calcium ions (Ca2+) combined in a 2:3 ratio to achieve a neutral charge.
If calcium and oxygen are in the same container, they would combine to form calcium oxide, which is a compound. Calcium and oxygen individually are elements, but when combined in a fixed ratio, they form a compound with different properties from the elements themselves.
The formula would be AlCl3, which is aluminum chloride.
Iron would not react with aluminum nitrate because iron is less reactive than aluminum and would not displace aluminum from its compound.
When naming the compound containing calcium and chlorine, the suffix of the atom name changes to "-ide." Therefore, the compound would be named calcium chloride.
As cations, they retain their original names (examples: aluminum chloride, sulfur dioxide). As anions, they get "ide" endings and become aluminide (very rare) and sulfide (not quite as rare). Combined with oxygen in complex anions, they form aluminates, sulfites, sulfates, etc.
Not by themselves, because they are both too electropositive. Together with oxygen, however, they form calcium aluminate.
If calcium and oxygen are in the same container, they would combine to form calcium oxide, which is a compound. Calcium and oxygen individually are elements, but when combined in a fixed ratio, they form a compound with different properties from the elements themselves.
It would be a compound, made of Calcium and Oxygen.
calcium chloride
A compound, and it's name would be calcium oxide.
The name would be calcium oxide and the chemical formula is CaO.
The formula would be AlCl3, which is aluminum chloride.
Iron would not react with aluminum nitrate because iron is less reactive than aluminum and would not displace aluminum from its compound.
CaPo is the chemical formula of calcium polonide.
Simply, this is aluminium sulfite. More formally it is aluminium(III) sulphate(IV).
When naming the compound containing calcium and chlorine, the suffix of the atom name changes to "-ide." Therefore, the compound would be named calcium chloride.
As cations, they retain their original names (examples: aluminum chloride, sulfur dioxide). As anions, they get "ide" endings and become aluminide (very rare) and sulfide (not quite as rare). Combined with oxygen in complex anions, they form aluminates, sulfites, sulfates, etc.
