Balance these equations?

1. 2NaCl + BeF2 --> 2NaF + BeCl2

2. 3NaOH + H3PO4 --> Na3PO4 + 3H2O

EDIT

Fe2(SO4)3 + KSCN --> K3Fe(KSCN)6 + K2SO4 is wrong

the actual reaction is - Fe2(SO4)3 + KSCN --> K3Fe(SCN)6 + K2SO4

so....

3. Fe2(SO4)3 + 12 KSCN = 2 K3Fe(SCN)6 + 3 K2SO4

2NaCl + BeF2 --> 2NaF + BeCl2

Can you see how easy balancing equations is? All you do is play around with the numbers till you have the same amount on each side of the -->

First look at sodium floride notice that sodium is already ballenced but F isn't because the berilium florite has 2 F's so if you put a 2 infront of both sodium groups (sodium = Na) then you keep Na ballanced and your F becomes ballanced. In advertantly Cl also became ballanced so were done.

haha i remember those days. My advice to you is to find out if your teacher gets the equations from a text book, and if so, get your hands on a teacher copy of the book with answers. Good luck
