4) 2K + Cl2 = 2KCl
5) 2Al + 6HCl = 2 AlCl3 + 3 H2
6) 2H3P04 + 3Ca(OH)2 = 6H20 + Ca3(PO4)2

K + Cl2 --> KCl
Al + HCl ---> AlCl3 + H2
Ca(OH)2 + H3PO4 ---> Ca3(PO4)2 + H2O
You can do the balancing.

4. 2K(s) + Cl2(g) = 2KCl(s)
5. 2Al(s) + 6HCl(g) = 2AlCl3(s) + 3H2(g)
6. 3Ca(OH)2(aq) + 2H3PO4(aq) = Ca3(PO4)2(s) +6H2O(l)
