0,55 moles of MgSO3 contain 57,40 g.
So far I come up with: HBr (aq) + MgSO3 (s) --> H2SO3 (aq) + MgBr2 (??)
The formula for magnesium hydrogen sulfite is: Mg(HSO3)2
The chemical formula for magnesium sulfate is: MgSO4
Likely it is; Magnesium sulfite Mg(2+) and SO3(2-) but SO3 can also be sulfur trioxide which also has an oxidation number of 2- then; Magnesium trioxide would be the name, but this is much less likely
MgO is ionic because it is a bond between a metal(Mg) and a non-metal(O).
The compound is ionic because Mg (magnesium) is a metal and S (sulfur) is a non metal with a relatively high electro-negativity.MgS [note correct letter cases] has ionic bonds.
Below are some tips on naming inorganic compounds H2S = Hydrogen sulphide K2S = Potassium sulphide FeS = Iron sulphide Li2S = Lithium sulphide K2SO3 = Potassium sulphite MgSO3 = Magnesium sulphite K2SO4 = Potassium sulphate Na2SO4 = Sodium sulphate KNO2 = Potassium nitrite KNO3 = Potassium nitrate As you see, anything without oxygen in the anionic portion of the compound lends IDE to the end, as in SULPHIDE As you see, the anion portion of the compound with the most oxygen lends ATE to the end as in SULPHATE. And one less oxygen lends ITE as in SULPHITE. Check this pattern with the nitrites and nitrates as well. One less oxygen gives the prefix HYPO in addition to the suffix ITE. One more oxygen than the normal ATE ending and you get the prefix PER and the suffix ATE. Examples LiCl = Lithium chloride LiClO = Lithium hypochlorite LiClO2 = Lithium chlorite LiClO3 = Lithium chlorate LiClO4 = Lithium perchlorate OH 1- ions lend the name hydroxide KOH = Potassium hydroxide Ca(OH)2 = Calcium hydroxide CO3 2- ions are carbonate ions CaCO3 = Calcium carbonate (NH4)2CO3 = Ammonium carbonate
To do this, you need to know the molecular weight of the element you're dealing with, by adding up the atomic weights of the elements involved (found on any periodic table). The molecular weight is the mass in grams of the compound in one mole - this will provide you with a conversion factor. So take the measurement in grams and divide it by the molecular weight to convert to moles. Really what you're doing is multiplying the number by 1 mole, and dividing it by the equivalent of one mole, the molecular weight. That's the thought process behind unit analysis and how you get your "units to cancel".In this case, the answer is about .4886 moles MgSO3.
