STEP 1
1. The chemical equation provided may not be balanced.
2. Balancing a chemical equation involves ensuring the same number of each type of atom appears on both sides of the equation.
3. The physical states of the compounds are given and should be maintained.
STEP 2
1. List the number of each type of atom on both sides of the equation.
2. Adjust coefficients to balance the atoms.
3. Verify that the equation is balanced.
STEP 3
List the number of each type of atom on both sides of the equation.
Left side:
- Mn: 1
- O: 3 (2 from and 1 from )
- H: 2
- Zn: 1
Right side:
- Mn: 1
- O: 4 (2 from and 2 from )
- H: 4
- Zn: 1
STEP 4
Adjust coefficients to balance the atoms.
To balance the oxygen and hydrogen atoms, we can adjust the coefficients of on the left side and and on the right side.
Let's start by balancing the oxygen and hydrogen atoms:
- Add a coefficient of 2 in front of on the left side to balance the hydrogen atoms.
- This gives us 4 hydrogen atoms on both sides, but now we have 4 oxygen atoms on the left side.
Now, the equation looks like this:
STEP 5
Verify that the equation is balanced.
Left side:
- Mn: 1
- O: 4 (2 from and 2 from )
- H: 4
- Zn: 1
Right side:
- Mn: 1
- O: 4 (2 from and 2 from )
- H: 4
- Zn: 1
The equation is now balanced with the same number of each type of atom on both sides.
