ok I'm going to do one... and explain, so you can do the rest by yourself, because giving you the answers won't help.
The Hardest one from there # 2
Ca(OH)2 + Na2SO4 = CaSO4 + 2 NaOH
It's simple, just combine the elements and use the Criss Cross method for the charges.
Switch the numerical values of the charge to create a neutral compound.
With this said, Ca has a +2 charge, and SO4 has a -2 charge as well, so both charges using the Criss Cross method are cancelled, then, you go the the next compound Na has +1 charge and OH a -1 so those charges are cancelled too. After finishing with the charges, just balance the equation.
