someone please helpp beg of you???

Question

balance the following two only
1)K(s) + H2O(l) ----> KOH(aq) + H2(g)
2) Al(s) + Fe2O3(s) -----> Al2O3 + Fe(s)

could you please balance and classify the next four equations..thanks a bunch!

1) ___P+ ___O2 -----> ____PO3
2)___Al + ___H2C03----> Al2(CO3)3 + ____H2
3)___NaClO3+____-----> NaCl + ___O2
4)____Ag2SO4 +____AlCl3----> ___AgCl + ___Al2(SO4)3

Answer 1

1) 2K(s) + 2H2O(l) ----> 2KOH(aq) + H2(g)
2) 2Al(s) + Fe2O3(s) -----> Al2O3 + 2Fe(s)

1) 2P+ 3O2 -----> 2PO3
2) 2Al + 3H2C03----> Al2(CO3)3 + 3H2
3) 2NaClO3+____-----> 2NaCl + 3O2
4) 3Ag2SO4 + 2AlCl3----> 6AgCl + Al2(SO4)3

Answer 2

1) 2K + H2O ---> 2KOH + H2
2) 2Al + Fe2O3 ----> Al2O3 + 2Fe


1) 2 + 3 ---> 2
2) 2 + 3 ---> 1 + 3
3) ???? but the answer would be 2 --->2 + 3
4) 4 =2 ---> 6 + 1
