The products of the reaction between zinc and sulfuric acid are zinc sulfate, hydrogen sulfide, and water. Balance the equation using the electron-transfer method.

Well, this chemical reaction sure knows how to make a splash! Let's dive in and balance this equation, shall we?

Zinc (Zn) always knows how to make an entrance, so we start with the unbalanced equation:

Zn + H₂SO₄ -> ZnSO₄ + H₂S + H₂O

Now, let's balance it out! We'll start by giving zinc (Zn) its moment in the spotlight. To make sure we're shining a light on both sides, we put a coefficient of "1" in front of Zn:

Zn + H₂SO₄ -> ZnSO₄ + H₂S + H₂O

Now, let's focus on the sulfuric acid (H₂SO₄) – it likes being the life of the party, so it gets two coefficients:

Zn + H₂SO₄ -> ZnSO₄ + H₂S + H₂O

And for the finale, let's ensure the products get equal attention. We'll add a coefficient of "1" in front of ZnSO₄, H₂S, and H₂O:

Zn + H₂SO₄ -> ZnSO₄ + H₂S + H₂O

Ta-da! It looks like we've balanced the equation with style and finesse. It's ready for the chemical red carpet!

To balance the equation between zinc and sulfuric acid, we need to ensure that the number of atoms of each element is the same on both sides of the equation. Here are the steps to balance the equation using the electron-transfer method:

Step 1: Write the unbalanced equation.
Zinc + Sulfuric acid → Zinc sulfate + Hydrogen sulfide + Water

Step 2: Balance the non-hydrogen and non-oxygen atoms.
Starting with the zinc and sulfuric acid, we have one zinc atom and one sulfur atom on the left side. On the right side, we have one zinc atom in zinc sulfate, one sulfur atom in zinc sulfate, and one sulfur atom in hydrogen sulfide. To balance the sulfur atoms, we need to add another sulfur atom to the left side.

Zinc + Sulfuric acid → Zinc sulfate + Hydrogen sulfide + Water
Zn + H2SO4 → ZnSO4 + H2S + Water

Step 3: Balance the hydrogen atoms.
We have two hydrogen atoms in sulfuric acid and two hydrogen atoms in water. To balance the hydrogen atoms, we need to add another hydrogen atom to the left side.

Zn + H2SO4 → ZnSO4 + H2S + H2O

Step 4: Balance the oxygen atoms.
We have four oxygen atoms in sulfuric acid and one oxygen atom in zinc sulfate. To balance the oxygen atoms, we need to add three oxygen atoms to the left side.

Zn + H2SO4 → ZnSO4 + H2S + 3H2O

Step 5: Check the equation.
Now, let's count the atoms on both sides of the equation to ensure they are balanced.

Left side: 1 Zn, 2 H, 4 O, 1 S
Right side: 1 Zn, 1 S, 1 S, 2 H, 3 O

All the atom counts are the same on both sides, so the equation is balanced.

The balanced equation using the electron-transfer method is:
Zn + H2SO4 → ZnSO4 + H2S + 3H2O

To balance the equation using the electron-transfer method, we need to determine the oxidation states of each element in the reactants and products.

In this reaction, zinc (Zn) is being oxidized from an oxidation state of 0 to +2, while sulfur (S) is being reduced from an oxidation state of +6 to -2. This indicates that electrons are transferred from zinc to sulfur.

Now let's balance the equation step by step:

Step 1: Write the unbalanced equation:

Zn + H2SO4 -> ZnSO4 + H2S + H2O

Step 2: Balance the least common atoms. In this case, hydrogen (H) and oxygen (O) are common between the sulfuric acid and the products:

Zn + H2SO4 -> ZnSO4 + H2S + H2O

Step 3: Balance the remaining atoms. Start with sulfur (S) since it is found in only one compound on both sides of the equation:

Zn + H2SO4 -> ZnSO4 + H2S + H2O

Step 4: Balance the zinc (Zn) atoms:

Zn + H2SO4 -> ZnSO4 + H2S + H2O

Step 5: Balance the hydrogen (H) atoms:

Zn + H2SO4 -> ZnSO4 + H2S + H2O

Step 6: Balance the oxygen (O) atoms:

Zn + H2SO4 -> ZnSO4 + H2S + H2O

The balanced equation is:

Zn + H2SO4 -> ZnSO4 + H2S + H2O
