Solution :
A) Ba3(PO4)2 (s) , H2O (l)
The balanced equation will be written as,
2H3PO4 + 3Ba(OH)2 = Ba3(PO4)3 (s) + 6H2O (l)
B) Sr(NO3)2 (aq) , AgCl(s)
The balanced equation will be written as,
SrCl2 (aq) + AgNO3(aq) = Sr(NO3)2 (aq) + 2AgCl(s)
C) K2S(aq) , H2O(l) , CO2(g)
The balanced equation will be written as,
2KHCO3(aq) + H2S(aq) == K2S (aq) +2 H2O(l) + 2CO2(g)
D) No reaction
