Question

MgCO3->MgO->Mg3(PO4)2->MgSO4

Answer 1

                 t

MgCO3 = MgO + CO2 

3MgO + P2O5 = Mg3(PO4)2

Mg3(PO4)2 + 3H2SO4 = 3MgSO4 + 2H3PO4

Answer 2

MgCO3=MgO+CO2

3MgO+2H3PO4=Mg3(PO4)2+3H2O

Mg3(PO4)2+Li2SO4=3MgSO4+2Li3PO4

Answer 3

The sequence you've provided appears to be a series of chemical reactions involving magnesium compounds. Let's break it down step by step:

1. MgCO3 -> MgO:

   • In this step, magnesium carbonate (MgCO3) decomposes to form magnesium oxide (MgO) through a thermal decomposition reaction. This reaction typically occurs when magnesium carbonate is heated:

   MgCO3 (s) -> MgO (s) + CO2 (g)

2. MgO -> Mg3(PO4)2:

   • In this step, magnesium oxide (MgO) reacts with phosphoric acid (H3PO4) to form magnesium phosphate (Mg3(PO4)2) and water (H2O). The balanced chemical equation for this reaction is as follows:

   3 MgO (s) + 2 H3PO4 (aq) -> Mg3(PO4)2 (s) + 3 H2O (l)

3. Mg3(PO4)2 -> MgSO4:

   • In this step, magnesium phosphate (Mg3(PO4)2) can react with sulfuric acid (H2SO4) to form magnesium sulfate (MgSO4) and phosphoric acid (H3PO4). The balanced chemical equation for this reaction is as follows:

   Mg3(PO4)2 (s) + 3 H2SO4 (aq) -> 3 MgSO4 (aq) + 2 H3PO4 (aq)

So, the overall sequence of reactions you've provided starts with magnesium carbonate (MgCO3) and results in the formation of magnesium sulfate (MgSO4) through a series of chemical reactions. These reactions involve decomposition, acid-base reactions, and precipitation reactions.
