Balance equation. been working on this for almost 5 hours now, just cant do it.

HCl+As2O3+NaNO3+H2O-->NO+H3AsO4+NaCl

Answer 1

Piece a cake.

Check out the site for balancing equations.
4HCl + 3As2O3 + 4NaNO3 + 7H2O --> 4NO + 6H3AsO4 + 4NaCl

Answer 2

To balance the given chemical equation:

HCl + As2O3 + NaNO3 + H2O → NO + H3AsO4 + NaCl

1. Start by balancing the atoms of each element in the equation.

HCl + As2O3 + 2NaNO3 + 3H2O → NO + H3AsO4 + 2NaCl

2. Balance the oxygen atoms by adding water molecules (H2O) where needed.

HCl + As2O3 + 2NaNO3 + 3H2O → NO + H3AsO4 + 2NaCl + 3H2O

3. Balance the hydrogen atoms by adding hydrogen ions (H+) where needed.

HCl + As2O3 + 2NaNO3 + 3H2O → NO + H3AsO4 + 2NaCl + 3H2O + 6H+

4. Balance the charge on each side of the equation by adding electrons (e-) where needed.

HCl + As2O3 + 2NaNO3 + 3H2O → NO + H3AsO4 + 2NaCl + 3H2O + 6H+ + 6e-

5. Verify that the number of atoms for each element and the overall charge (including the electrons) are balanced on both sides of the equation.

2Cl + 2As + 6O + 2Na + 3H + 6e- → N + H3AsO4 + 2NaCl + 3H2O + 6H+ + 6e-

The equation is now balanced.

Answer 3

Balancing chemical equations can sometimes be challenging, but there are systematic steps you can follow to solve them. Let's break it down and go through the process step-by-step.

The unbalanced equation you provided is:
HCl + As2O3 + NaNO3 + H2O --> NO + H3AsO4 + NaCl

Step 1: Count the number of atoms of each element on both sides of the equation. This will help you identify which elements need to be balanced.

HCl + As2O3 + NaNO3 + H2O --> NO + H3AsO4 + NaCl
1 2 3 1 1 1 1
1 2 1 3 1 1 1

Step 2: Start balancing with elements that appear in the fewest compounds. In this case, we can start with H (hydrogen).

On the left side, we have 1 H atom from HCl and 2 H atoms from H2O. To balance that, we need two HCl molecules:
HCl + HCl + As2O3 + NaNO3 + H2O --> NO + H3AsO4 + NaCl

H atoms: 2
Cl atoms: 2

Step 3: Next, balance the O (oxygen) atoms.
On the left side, we have 3 O atoms from NaNO3 and 1 O atom from H2O. To balance that, we need three H2O molecules:
HCl + HCl + As2O3 + NaNO3 + 3H2O --> NO + H3AsO4 + NaCl

H atoms: 6
Cl atoms: 2
O atoms: 9

Step 4: Balancing the As (arsenic) atoms.
On the right side, we have 1 As atom from H3AsO4. To balance that, we need one As2O3 molecule:
HCl + HCl + As2O3 + NaNO3 + 3H2O --> NO + H3AsO4 + NaCl

H atoms: 6
Cl atoms: 2
O atoms: 9
As atoms: 2

Step 5: Balancing the Na (sodium) atoms.
On the right side, we have 1 Na atom from NaCl. To balance that, we need one NaNO3 molecule:
HCl + HCl + As2O3 + NaNO3 + 3H2O --> NO + H3AsO4 + NaCl

H atoms: 6
Cl atoms: 2
O atoms: 9
As atoms: 2
Na atoms: 1

Step 6: Balancing the NO (nitric oxide) molecule.
On the right side, we have 1 NO molecule. To balance that, we need one NO molecule on the left side:
HCl + HCl + As2O3 + NaNO3 + 3H2O --> NO + H3AsO4 + NaCl + NO

H atoms: 6
Cl atoms: 2
O atoms: 9
As atoms: 2
Na atoms: 1
NO molecules: 2

Step 7: Finally, check if all elements are balanced. In this case, they are.

The balanced equation is:
2HCl + As2O3 + NaNO3 + 3H2O --> 2NO + H3AsO4 + NaCl

It is always a good idea to double-check the coefficients in the balanced equation to ensure everything has been balanced correctly.
