How do you balance ZnCO3 +O2 yields ZnO + CO2?

znco3+o2

In three words, not very easily. You don't need the O2.

ZnCO3 + heat --> ZnO + CO2

To balance the chemical equation ZnCO₃ + O₂ → ZnO + CO₂, follow these steps:

Step 1: Count the number of zinc (Zn) atoms on both sides. There is 1 Zn atom on the left side and 1 Zn atom on the right side, so no further adjustment is needed for Zn.

Step 2: Now, look at the carbon (C) atoms. There is 1 C atom on the left side and 1 C atom on the right side, so no further adjustment is needed for C.

Step 3: Examine the oxygen (O) atoms. There are 3 O atoms in ZnCO₃ on the left side, but only 2 O atoms in ZnO + CO₂ on the right side. To balance the O atoms, we need to add CO₂.

Step 4: Add a coefficient of 2 in front of CO₂ on the right side to balance the O atoms. Now, there are 2 C atoms and 4 O atoms on each side.

ZnCO₃ + O₂ → ZnO + 2CO₂

The equation is now balanced with 1 Zn atom, 1 C atom, and 4 O atoms on both sides.

To balance the chemical equation ZnCO3 + O2 → ZnO + CO2, you need to make sure that there is an equal number of each type of atom on both sides of the equation. Here's how you can balance this equation step by step:

1. Start by counting the number of each type of atom on either side of the equation.
On the left side, we have 1 zinc (Zn), 1 carbon (C), and 3 oxygen (O) atoms. On the right side, we have 1 zinc (Zn), 1 carbon (C), and 2 oxygen (O) atoms.

2. Begin by balancing the most complex molecule or any molecule containing the largest number of different atoms. In this case, it is ZnCO3.

3. To balance carbon (C), place a coefficient of 1 in front of CO2 on the product side. Now we have: ZnCO3 + O2 → ZnO + 1CO2

4. Next, balance the zinc (Zn). Since there is already one Zn atom on each side of the equation, it's already balanced.

5. Finally, balance oxygen (O). On the reactant side, there are 3 O atoms from ZnCO3 and 2 O atoms from O2, giving a total of 5 O atoms. On the product side, there are 2 O atoms from ZnO and 1 O atom from CO2, giving a total of 3 O atoms.
To balance the oxygen, place a coefficient of 5/2 or 2.5 in front of O2 on the reactant side. This will give us: 2.5O2.

Now the balanced equation is: ZnCO3 + 2.5O2 → ZnO + CO2

However, it is not possible to have a fractional coefficient in a balanced equation. So, multiply the entire equation by 2 to eliminate the fraction:

2ZnCO3 + 5O2 → 2ZnO + 2CO2

Thus, the balanced chemical equation for the reaction ZnCO3 + O2 → ZnO + CO2 is 2ZnCO3 + 5O2 → 2ZnO + 2CO2.
