Best Answer

Mg3(C6H5O7)2 is the molecular formula for magnesium citrate. Magnesium is a Group IIA element and like all members of this group readily ionizes to Mg+2. C6H5O7 is the formula for the polyatomic citrate ion which has a negative three charge. Molecules are stable combination of atoms that are electronically neutral. It takes three Mg+2 to cancel out the charge of two C6H5O7-3.

Parenthesis are placed around the citrate ion to show that the subscript 2 only applies to the citrate ion.

What is the chemical equation of magnesium and phosphorus acid?

3Mg(s) + 2H3PO4(aq) ---> 3H2(g) + Mg3(PO4)2(s)I believe the equation is: Mg + H3PO4 ---> H2 + Mg3PO4. It should be Mg3(PO4)2 because magnesium has a charge of +2 (Mg+2), and phosphate has a charge of -3 (PO4-3), which would become Mg3(PO4)2. Balanced, the equation is 3Mg + 2H3PO4 ---> 3H2 + Mg3(PO4)2

What is the net ionic equation for sodium phosphate and magnesium nitrate?

The net ionic equation for this reaction is:3Mg2+(aq) + 2PO43-(aq) -->Mg3(PO4)2(s)How to get this answer:To write the net ionic equation, you can start with the molecular equation:2Na3PO4(aq) + 3Mg(NO3)2(aq) --> 6NaNO3(aq) + Mg3(PO4)2(s)The molecular equation can be used to write the full ionic equation. To do this, you break down everything that is aqueous into its ionic constituents:2Na+(aq) + 2PO43-(aq) + 3Mg2+(aq) + 6NO3-(aq) --> 6Na+(aq) + 6NO3-(aq) + Mg3(PO4)2(s)You can then cross out whatever is the same on both side to get your net ionic equation:3Mg2+(aq) + 2PO43-(aq) -->Mg3(PO4)2(s)
