how to balance ZnO+2HCl yields ZnCl2+H2O
that equation is already balanced :/
I agree with Desiree. The equation is balanced.
To balance the given chemical equation ZnO + 2HCl → ZnCl2 + H2O, you need to ensure that there is an equal number of atoms of each element on both sides of the equation. Here's how you can balance it:
1. Start by counting the number of atoms for each element on both sides of the equation:
Zn: 1 on the left, 1 on the right
O: 1 on the left
H: 2 on the right
Cl: 1 on the left, 2 on the right
2. Begin by balancing the atoms appearing in the least number, which in this case is Zn. Since there is an equal number of Zn atoms on both sides, move on to the next element, which is O.
3. To balance oxygen (O), place a coefficient of 1/2 in front of the ZnO on the left side of the equation:
1/2 ZnO + 2HCl → ZnCl2 + H2O
4. Now, let's check the hydrogen (H) and chlorine (Cl) atoms. We have 2 hydrogen atoms on the right and none on the left, and we have 2 chlorine atoms on the right and 2 on the left. Therefore, we don't need to make any further changes.
The final balanced equation is:
1/2 ZnO + 2HCl → ZnCl2 + H2O
This equation demonstrates the balanced reaction between zinc oxide (ZnO) and hydrochloric acid (HCl), producing zinc chloride (ZnCl2) and water (H2O).
