What are your ideas.

Final is

Sn + 2 NaNO3 => SnO2 + 2 NaNO2

Sn + 2 NaNO 3 => SnO 2 + 2 NaNO 2 is the most accurate.

Why repetition. It's already written above.

Copper(I)sulfate is not existing.
The equilibrium is on left right side
Cu2SO4 =======> CuSO4 + Cu

To balance the given chemical reaction using the electron balance method, we first need to identify the oxidation states of the elements involved and determine which species are being oxidized and which are being reduced. The reaction is:
Sn+NaNO3→SnO2+NaNO2

Step 1: Assign oxidation states

Sn: In its elemental form, Sn has an oxidation state of 0. In SnO2SnO2​, Sn has an oxidation state of +4.

Na: In NaNO3NaNO3​ and NaNO2NaNO2​, Na has an oxidation state of +1.

N: In NaNO3NaNO3​, N has an oxidation state of +5. In NaNO2NaNO2​, N has an oxidation state of +3.

O: Oxygen has an oxidation state of -2 in both compounds.

Step 2: Identify the oxidizing and reducing agents

Sn is being oxidized from 0 to +4 (loses 4 electrons).

N in NaNO3NaNO3​ is being reduced from +5 to +3 (gains 2 electrons).

Thus:

Oxidizing agent: NaNO3NaNO3​ (causes oxidation by accepting electrons).

Reducing agent: SnSn (causes reduction by donating electrons).

Step 3: Balance the electrons

Sn loses 4 electrons: Sn→Sn4++4e−Sn→Sn4++4e−.

Each N in NaNO3NaNO3​ gains 2 electrons: N5++2e−→N3+N5++2e−→N3+.

To balance the electrons, we need 2 N atoms to accept 4 electrons (since 2 × 2 = 4). Therefore, we need 2 NaNO3NaNO3​ molecules.

Step 4: Write the balanced equation

Sn+2NaNO3→SnO2+2NaNO2

Step 5: Verify the balance

Sn: 1 on both sides.

Na: 2 on both sides.

N: 2 on both sides.

O: 6 on both sides.

The equation is balanced.

Final Answer:
Sn+2NaNO3→SnO2+2NaNO2

Oxidizing agent: NaNO3NaNO3

Reducing agent: SnSn

The answer was already given above. No need to repeat it.
