There are a few methods, most of them require memorization, or a good chart.  For example, ionic compounds get named by adding the names of their ions, but molecular compounds get named by each individual element and a prefix of how many there are.  Then you have acids...  \n\nhere are some examples:\n\nNaCl - Sodium Chloride\nNa2CO3 - Soduum Carbonate\nNa3PO4 - Sodium Phosphate\n\nNotice that sodium is always sodium, not mono, di or tri.\n\nMolecular compounds are different, here are some examples:\n\nNF3- nitrogen trifluoride   \nNO - nitrogen monoxide OR nitric oxide (Ionic)\nNO2 - nitrogen dioxide  \nN2O - dinitrogen monoxide (laughing gas)\n\nI wont even go into acids, or Hydrocarbons\n\nI hope that gets you started anyway

a) Nitrate is a conjugate base of Strong acid HNO3.  Therefore, NO3- is a weak base.\n\nb) Cyanide is a conjugate base of a weak acid HCN.\nTherefore, CN- is a relatively strong base.\n\nc) Ammonium is a conjugate acid of a weak base NH3.\nTherefore, NH4+ is a strong acid.\n\nd) Chloride ion is a conjugate base of a strong acid HCl.\nTherefore, Cl- is a weak base.

What the above guys are talking about is valence, as far as I know there are no nitrogen ions, an ion is a charged particle, that has completely taken or given up electrons but DOES NOT share them, for example the chloride ion. However all of the nitrogen compounds I know (and I must accept I don't know it all) share their electrons

Alkali metals and alkali earth metals tend to form ionic bonds.  They have a +1 or +2 charge.\n\nThe halogens normally form ionic bonds when "joined" with a IA or IIA metal.\n\nTransition metals normally are ionic.\n\nNow for the trick part:  Carbon and nitrogen generally form covalent bonds.  When joined with other elements, they can produce a neutral molecule (CO, CO2).  But they also form polyatomic ions (C03- (carbonate); NO3- (nitrate) ).  \n\nGeneral rule of thumb - IA, IIA, and VIIA atoms will make ionic bonds.  \n\nHope this helps!

Co(NH3)4 would be more likely

Carbonic anhydrase (carbonate dehydratase) is a family of metalloenzymes (enzymes that contain one or more metal atoms as a functional component of the enzyme) that catalyze the rapid interconversion of carbon dioxide and water into carbonic acid, protons, and bicarbonate ions. This reaction occurs spontaneously in aqueous solution, but does so slowly. Carbonic anhydrase can increase the rate of the reaction about a million-fold. The active site of most carbonic anhydrases contains a zinc ion.

CCl4 is not a Lewis acid as it cannot accept electrons.\n\nBoth silicon and tin can expand their octets to accomodate more electrons, so they can act as Lewis acids.  Carbon cannot.

complex ions - which then form ionic molecules

What the first reply means is that since it is ionic, it does not have a molecular shape.  It is NOT a molecule.  The Zn+2 ion and the Br- ions will form crystals.  They have a unit formula of ZnBr2 (not znbr2) but it is not a molecule.

In chemistry, an ionic compound is a chemical compound in which ions are held together in a lattice structure by ionic bonds. The positively charged ion is usually a metal ion and the negatively charged ion is non-metallic element or molecule.\n\nIons can be single atoms, as in common table salt sodium chloride, or more complex groups such as calcium carbonate. But to be considered ions, they must carry a positive or negative charge.\n\nThus, in an ionic bond, one 'bonder' must have a positive charge and the other a negative one. By sticking to each other, they resolve, or partially resolve, their separate charge imbalances. Positive to positive and negative to negative ionic bonds do not occur. (For a real world analogy, experiment with a pair of bar magnets.)

there are 2 pi  & 1 sigma bond in cn & 1 pi & 1 sigma bond in co

you are in the wrong section!!! this is math section...u need to go chemistry section....\n\nAnyway, the formula for cobalt(III)chloride plus ammonia is........\n\nCoCl3 + NH3 = NCo + 3HCl
