Comment on O Level Chemistry: Mole Calculations – Balanced Chemical & Ionic Equations by Varda

a)CuO+H2SO4–>CuSO4+H20(already balanced)
b)Cu(2+)+O(2-)+2H(1+)+SO4(2-)–>Cu(2+)+SO4(2-)+H20
Therefore,the ionic equation is: 2H(1+) + O(2-)–>H20
The spectator ions are Cu(2+) and SO4(2-)

Sean,i hope these are the correct answers but i have a little confusion about souluable and insoluable bases.can u tell which are soluable and insoluable cuz i cant find them anywhere.
Thanx!
