Question

are these net ionic equations balanced?
1. NaC2H3O2 + HNO3 ----> NaNO3 + HC2H3O2
C2H3O2- + H+ ----> HC2H3O2
2. Pb(NO3)2 + (NH4)2SO4 ----> PbSO4 + 2NH4NO3
2NO3- + 2NH4+ ----> 2NH4NO3
3. H2S + Cu(NO3)2 ----> 2HNO3 + CuS
S+ + Cu- ----> CuS
4. NaOH + NH4Cl ---> NH3 + H20 + NaCl
OH- + NH4+ ---> NH3 + H20

Answer 2

Actually, it would be much better if you can show the equations separately and clearly....
1. NaC2H3O2 + HNO3 ----> NaNO3 + HC2H3O2
For the left side,
No. of Na = 1
No. of C = 2
No. of H = 3+1 = 4
No. of O = 2 + 3 = 5
No. of N = 1

For the right side,
No. of Na = 1
No. of C = 2
No. of H = 1+3 = 4
No. of O = 3+ 2 = 5
No. of N = 1

Then consider the charge of both sides
NaC2H3O2 + HNO3 ----> NaNO3 + HC2H3O2
0 0 0 0
For LHS, total charge = 0+0 = 0
For RHS, total charge = 0+0 = 0
LHS = RHS

No. of different atom remains the same + charge are balanced => balanced

C2H3O2- + H+ ----> HC2H3O2
charge: -1 +1 0
Total charge of LHS = -1+1 =0
Total charge of RHS = 0 = LHS

For LHS
No. of H atom = 3+1 = 4
No. of C atom = 2
No. of O atom = 2

For RHS
No. of H atom = 1+3 = 4
No. of C atom = 2
No. of O atom = 2

No. of different atom remains the same + charge are balanced => balanced

So, for 1, they are balanced.
Can you try the rest?

Answer 3

@Callisto I appreciate your concern about how I balance my equations but I am comfortable with what I have and do, and I am talking about net ionic equations, I need someone to check if they are correct.

Answer 4

@bronzegoddess Well, seems I've misunderstood your question. But please make the equations clear first. For example, I believe that ''NaC2H3O2 + HNO3 ----> NaNO3 + HC2H3O2 C2H3O2- + H+ ----> HC2H3O2'' are two equations while they are actually NOT separated. It's hard to follow.

Answer 5

@Callisto okay, I'll do that then.

Answer 6

its not letting me change then well, so i'll post them down here
1. NaC2H3O2 + HNO3 ----> NaNO3 + HC2H3O2
C2H3O2- + H+ ----> HC2H3O2
2. Pb(NO3)2 + (NH4)2SO4 ----> PbSO4 + 2NH4NO3
2NO3- + 2NH4+ ----> 2NH4NO3
3. H2S + Cu(NO3)2 ----> 2HNO3 + CuS
S+ + Cu- ----> CuS
4. NaOH + NH4Cl ---> NH3 + H20 + NaCl
OH- + NH4+ ---> NH3 + H20

Answer 7

2 is wrong, 3 is wrong, 4 should be okay. Still checking 1.
BTW, please include the state of the substances.

Answer 8

1 should be okay too.

Answer 9

For (2), the salt you've chosen is soluble. Instead, PbSO4 is insoluble.
For (3) the S is 2-, not + , Cu should be of a charge 2+

Answer 10

okay thank you! I'll redo them :)

Answer 11

welcome!

Answer 12

I unfortunately don't know chemistry. Sorry.
