Home / great magnesium carbonate is heated

Jul 05, 2010 · a mixture of calcium carbonate and magnesium carbonate, with a mass of 10g, was heated to constant mass, with the final mass being 5.096g. i need to know the percentage composition of the mixture,...

Oct 14, 2009 · when magnesium metal wire is heated in open air, an oxidation-reduction reaction takes place between the magnesium and the oxygen in the air. the magnesium is oxidized as the oxygen is reduced. the product of this reaction is magnesium oxide, mgo.
Several authors have investigated latent heat storage by these materials with phase change temperatures in the above range, and focused on a mixture of magnesium nitrate hexahydrate as a base material and magnesium chloride hexahydrate as an additive to modulate the melting point. addition of 5–10 wt% of the latter resulted in a modulated melting point of around 80 °c and a heat
