molecular weight of NiSO4.7H2O is 1101.3 and it has 11 oxygens.

So percentage of oxygen = (7 x 16) / 1101.3 = 112 / 1101.3 = 0.102 or 10.2%

When are roman numerals used in chemistry and compound naming?

directly.. roman numerals are used for transitional metals becasue they can take on more than one charge. The naming of compunds depends on what type of compound you are naming, first, lets look at non-transitional metals from the groups Ia and 2a becasue they do not take on more than one type of charge. ( these are ionic compounds) and please note that the cation is always wrttien before the anion! When a metal and a non-metal bond they make ionic bonds -that is one gives up an eletron and one gains an eletron thus making it more stable. The rules for naming binary ionic compounds( contain only two different elements) ( groups Ia (+1) and 2a (+2)) > the metal keeps it full name >> the non-metal ends with ide for example: KCl -> Potassium Chloride In going backward the charges MUST equal ZERO! example: Sodium Chloride Na^+1 + Cl^-1 -> NaCl 1+-1 =0 For transitional metals it must be noted that these metals can take on different charges I =+1 II =+2 copper (II) = cu^+2 IV=+6 The same rules apply as before but the charge must be inculded Copper(II) Oxide To go back the charges must equal ZERO Copper(II) Oxide cu^+2 + O ^-2 -> CuO Naming Polyatomic Ions .. the name of the metal and the polyatomic ion remain the same example NaNO2 -> Sodium Nitrite FeSO4 -> iron(II) sulfate NH4NO3 -> ammonium nitrate Hydrated ionic compounds some ionic compounds called hydrates contain specific number of water molecules associated with each formula unit. an example, is epsom salts MgSO4 times 7H2O) = magnesium sulfate heptahydrate. So, it the rules stay the same with the addition of hydrate common hydrate prefixes hemi=1/2 mono=1 di=2 tetra=4 penta=5 hexa=6 hepta=7 Naming molecular compounds (are usually composed of two or more covalently bonded nonmetals). The first step is to identify it! (prefix)(name of first element) (prefix) (name of second element) * when the frist prefix is mono it is usually left out! NO2 -> Nitrogen dioxide N20-> dinitrogen monooxide Naming Acids Binary acids are composed of hydrogen and a nonmetal (Hydro) ( base name of metal with ic ) (acid) HCl -> Hydrochloric acid Naming Oxyacids Oxyanions ending with -ate (base name of oxyanion + ic) (acid) Oxyanions ending with -ite ( base name of oxyanion +ous) (acid) HNO3 ( NO3 = nitrate) nitric acid H2SO3 (SO3 = sulfite) sulfurous acid
