Write a balanced net ionic equation.

Ca(OH)2 (aq) + H3PO4 (aq) (Weak Acid)  →  CaHPO4 (aq) + H2O (l)

SrBr2 (aq) + (NH4)2CO3 (aq)  →  SrCO3 (s) + NH4Br (aq)

Al(OH)3 (s) + HBr (aq)  →  AlBr3 (aq) + H2O (l)

Al (s) + HCl (aq)  →  AlCl3 (aq) + H2 (g)

Answer #1

1) Ca(OH)2 (aq) + H3PO4 (aq) (Weak Acid)  →  CaHPO4 (aq) + 2H2O (l)

2H+(aq) + 2OH-(aq) ------------> 2H2O(l) net-ionic equation as follows

2)  SrBr2 (aq) + (NH4)2CO3 (aq)  →  SrCO3 (s) + 2NH4Br (aq)

Sr+2(aq) + CO3-2(aq) ----------->   SrCO3 (s)

3)  Al(OH)3 (s) + 3HBr (aq)  →  AlBr3 (aq) + 3H2O (l)

3H+(aq) + 3OH-(aq) ------------> 3H2O(l)

4) 2Al (s) + 6HCl (aq)  →  AlCl3 (aq) + 3 H2 (g)

2Al(s) + 6H+(aq) ---------> 2Al+3(aq) + 3H2(g)
