Generally, the elements that form ionic bonds tend to have either very high or very low electronegativity. This means the Alkali metals, Alkaline Earth metals, and the Halogens, especially when reacting with each other.

1. Aldehydes, such as formaldehyde, glutaraldehyde.\n\n2. Oxidizing agents: metallic ions and complexes, such as osmium tetroxide, chromic acid.\n\n3. Protein-denaturing agents, such as acetic acid, methyl alcohol (methanol), ethyl alcohol\n   (ethanol).\n\n5. Microwaves.

That's easy. [Co(NH3)6]Cl3. This is coordination chemistry, dude. There can be other products depending on the ammonia concentration. But this is your best bet. I've been doing these reaction in the lab way way back.

Ammonium (NH4+) is a polyatomic ion.  That means that it is composed of a group of atoms that are covalently bound together.  As a whole, that group has a charge of +1.  \n\nBecause this group of atoms has a charge, it is an ion, and can form ionic bonds with other ions.  So in summary, ammonium itself is a covalent compound, but it is able to form ionic bonds with other substances.

Binary: NaCl  (sodium chloride)\nPolyatomic cation:  NH4Cl  (ammonium chloride)\nPolyatomic anion:  Li2SO4  (lithium sulfate)\nPolyatomic complexed:  (NH4)3PO4  (ammonium phosphate)\nThey might be broken down differently to include inorganic and organic.  Their are also compounds called Zwitterions which contain both cation and anion.

in order:\nammonium chloride\ncalcium nitrate\nIron(III)hydroxide(this will turn to Fe2O3 fast which is rust)\nSodium carbonate\npotassium sulfate\nammonium sulfate\nI think you mean: Ca(NO3) with this one which is calcium nitrate\nand the last one is magnesium nitrite(not nitrate)

ammonium nitrate and aluminum hydroxide\n\nNH4NO3 + Al(OH)3\n\nThe aluminum hydroxide is insoluble when formed and will precipitate out of the solution as a solid powder.

Ionic compounds (like NaCl) for lattice structures.  These lattice structures make up the crystaline arrangement of the compound.\n\nThe lattice of NaCl looks like a cube,\nhttp://zimmer.csufresno.edu/~davidz/Chem3AF97/ChB/IonicBond.html\nhttp://departments.kings.edu/chemlab/chemlab_v2/nacl.html

Huge order. Let's see how far it can be served.\n\n1. Monoatomic negative ions: take the element name (sometimes shortened) and add "-ide" (as in hydride, nitride, oxide, sulphide, phosphide, chloride...)\nPositive ions: element-name, charge (if several charges are possible), ion (sodium ion, iron II ion...)\n\n2. Polyatomic ions:\nComplexes with various ligands list the ligands and the central ion/atom.\nOxygen as ligands has its own nomenclature, depending on oxidation state. E.g. Sulphate, sulphite, perchlorate, chlorate, chlorite, hypochlorite...\n\n3. Binary molecular compounds: Halogen, oxygen and sulphur compounds usually have the correspondent "-ide" as if you had ionic compounds. Usually the more electropositive element is used as center.\n\n4. Acids: Oxygen acids have a similar nomenclature to oxygen ions.
