Answer 2

First, we have to balance the equation. :3 This one is simple. Can you see it?

Answer 3

It looks like cn and 2so4 are switched c:

Answer 4

Switched? .-. Yah, this is a displacement reaction, but we need the same number of atoms on each side. ;-;

Answer 5

So do I jus make up numbers until it fits?

Answer 6

H-2. H-1
S-1. S-1
O-4. O-4
Na-1. Na-2
C-1. C-1
N-1. N-1

I forgot how to make them match though.....

Answer 7

@iPwnBunnies don't I add 2 to the first part of the second equation.
H-2. H-2
S-1. S-1
O-4. O-4
Na-1. Na-2
C-1. C-2
N-1. N-2
And then I add 2 to the front of the first probem
H-2. H-2
S-1. S-1
O-4. O-4
Na-2. Na-2
C-2. C-2
N-2. N-2
And then they're even? Did I do that right?... Ten what do I do?
