Pb3(PO4)2 i just answered it on castlelearning.com and it was correct
Pb3(PO2)2
Cu3(PO2)2
(H2PO2)- is the chemical formula of the hypophosphite anion.
It is a double replacement reaction: 2Na3PO2 + 3CuSO4 --> Cu3(PO2)2 + 3Na2SO4. The products are copper(II) hypophosphite and sodium sulfate.
Pb(ClO3)4
The chemical formula of lead(IV) carbonate is Pb(CO3)2.
Fe(H2Po2)2
Cu3(PO2)2
Fe(H2PO2)2
Formula: Ca(H2PO2)2
(H2PO2)- is the chemical formula of the hypophosphite anion.
This is the manganese phosphinate (hypophosphite).
There are two lead phosphates: lead (II) metaphosphate with formula Pb(PO3)2 and lead (II) orthophosphate with formula Pb3(PO4)2
It is a double replacement reaction: 2Na3PO2 + 3CuSO4 --> Cu3(PO2)2 + 3Na2SO4. The products are copper(II) hypophosphite and sodium sulfate.
Pb(ClO3)4
The chemical formula of lead(IV) carbonate is Pb(CO3)2.
Lead acetate's chemical formula is Pb(CH3COO)2
Lead (II) bisulfate has the formula Pb(HSO4)2
