Completing & balancing an equation

[fischteach]

Please help me "complete & balance" these equations:

K₃ PO₄(aq) + MgCl₂(aq)=

Fe(NO₃)₃(aq) + Na₂ CO₃(aq)=

Thanks!

1)

Code: Select all

2 K3PO4(aq) + 3 MgCl2(aq) = 6 KCl(aq) + Mg3(PO4)2(s)

2)

Code: Select all

2 Fe(NO3)3(aq) + 3 Na2CO3(aq) = Fe2(CO3)3(s) + 6 NaNO3

Hope this helps,

Hey;) I'm looking for some help. Could you finish these two chemical equations:

KBr (aq) + KMnO₄ (aq) + H₂SO₄ (aq) =>

NaI (aq) + KMnO₄ (aq) + KOH (aq) => ?

Thank you:)
