Translating word equations/naming compounds -- by Ria Park

Sometimes we need to translate balancing equations into word equations. There are some rules that they have to follow.

For ionic compounds:
NaCl -> Sodium Chloride
MgCl₃ -> Magnesium Chloride
Fe₂O₃-> Iron(Ⅱ) Oxide

  • Put '-ide' at the and of the names of non-metals


For Covalent Compounds:
mono  1
di        2
tri        3
tetra    4
penta  5
hexa   6                      >> Put any of these infront of the names of non-metals
hepta  7
Octa   8
nona   9
deca   10
hendeca  11
dodeca    12

CO₂Carbon dioxide
CO   carbon monoxide


Acids:
HCl  Hydro chloric acid
H₂SO₄Sulfuric aicd
H₂SO₃Sulfurous acid
HNO₃Nitric acid

  •  --ate -> --ic
  • --ite -> --ous


E.g.

  1.  Cu + 2AgNO₃-> Cu(NO₃)₂+ 2Ag  ==>> Copper + silver nitrate -> copper nitrate + silver
  2. Cu + I -> CuI ==>> Copper + Iodine -> Copper Iodide
  3. C₃H8 + O₂ -> CO₂+ H₂O ==>> Trioxide Octahydride -> Carbon dioxide + water
