Answer:
2K3PO4(aq) + 3MgCl2(aq) → Mg3(PO4)2(s) + 6KCl(aq)
Explanation:
K3PO4(aq) + MgCl2(aq)→ Mg3(PO4)2(s) + KCl(aq) (unbalanced)
2K3PO4(aq) + 3MgCl2(aq) → Mg3(PO4)2(s) + 6KCl(aq)
Reactants: Products:
K: 3x2=6 K: 1x6=6
P: 1x2=2 P: 1x2=2
O: 4x2=8 O: 4x2=8
Mg: 1x3=3 Mg: 3x1=3
Cl: 2x3=6 Cl: 1x6=6
Therefore the equation is balanced. Hope this helps.
