When magnesium carbonate dissolves in dilute mineral acids, it evolves carbon dioxide: MgCO3+HCl⇒MgCl2+CO2(gas)+H2O MgCO3+H2SO4⇒MgSO4+CO2(gas)+H2O When heated above 360°C, CO2andmagnesium oxideare formed: MgCO3⇒MgO+CO2 The trihydrate, MgCO3·3H2O or other hydrates when heated form...
2 A student adds excess large pieces of magnesium carbonate, MgCO , to dilute hydrochloric acid,HCL, and measures the volume of carbon dioxide gas, CO2, given off.(a)Add the missing state symbols to the chemical equation for the reaction.MgCO3... + 2HC1...→MgCl2(aq) + H2O... + ...
(d) A student prepares crystals of magnesium chloride by adding an excess of magnesium carbonate to 50.00 cm3 of 2.00 mol/dm3 hydrochloric acid.The student filters the mixture and rinses the residue.(i)Why does the student add an excess of magnesium carbonate?...[1](ii) Why does the stu...
it is difficult to ignite in mass or bulk. Once ignited, it is difficult to extinguish, being able to burn in nitrogen (forming magnesium nitride), carbon dioxide (forming magnesium oxide and carbon) and water (forming magnesium oxide and hydrogen). This property ...

Mg(OH)2(s) + 2 HCl (aq) 🡪 MgCl2(aq) + 2 H2O (l) Magnesium carbonate can substitute magnesium hydroxide in a similar reaction. However, as a by-product, carbon dioxide will also be produced along with water. Here is the chemical formula- ...
The objective of this post hoc evaluation of the CALcium acetate MAGnesium carbonate (CALMAG) study was to compare the effects of calcium acetate/magnesium carbonate (CaMg) and a calcium-free phosphate binder, sevelamer-hydrochloride (HCl), on serum levels of fibroblast growth factor-23 (FGF-23...
