Well, we must balance mass and balance charge...

Explanation:

#a.# #KOH(aq) + HBr(aq) rarr KBr(aq) + H_2O(l)#

#b.# #Ba(OH)_2(s) + H_2SO_4(aq) rarr BaSO_4(s)darr + 2H_2O(l)#

#c.# #Ca(OH)_2(s) + 2HNO_3(aq) rarr Ca(NO_3)_2(aq) + 2H_2O(l)#

#d.# #Cu(OH)_2(s) + Delta rarr CuO(s) + H_2O(l)#

#e.# #Fe(OH)_3(s) + 3HCl(aq) rarr FeCl_3(aq) + 3H_2O(l)#

I had to guess for the last example....

Refer to the explanation.

Explanation:

#"a."# #"KOH(aq) + HBr(aq)"##rarr##"KBr(aq) + H"_2"O(l)"#

#"b."# #"Ba(OH)"_2("s") + "H"_2"SO"_4("aq")##rarr##"BaSO"_4("s")darr + "2H"_2"O(l)"#

#"c."# #"Ca(OH)"_2("s") + "2HNO"_3("aq")"##rarr##"Ca(NO"_3)_2("aq") + "2H"_2"O(l)" + "heat"#

#"d."# #"Cu(OH)"_2("s") + "heat"##rarr##"CuO(s) + H"_2"O(l)"#

#"e."# #"2Fe(OH)"_3("s") + "heat"##rarr##"Fe"_2"O"_3 + "3H"_2"O"#
