is this correct?:
word equation:
nitric acid+potassium hydroxide= potassium nitrate
balanced symbol equation:
3HNO3+2KOH=2KNO3+H2O
> balanced symbol equation:
> 3HNO3+2KOH=2KNO3+H2O
You may want to check out the balancing of each side. Hints in bold.
so its
>2HNO3+2KOH=2KNO3+H2O?
Now the NO3 and the K are balanced. So you have 4H and 2O remaining on the left, and H2 on the right.
What would you change to make it balance?
erratum: "... and H2O on the right"
Yes, your word equation and balanced symbol equation are both correct. The word equation states that nitric acid reacts with potassium hydroxide to produce potassium nitrate. The balanced symbol equation provides the chemical formula and the coefficients of each compound involved in the reaction.
To check if the balanced symbol equation is correct, follow these steps:
1. Count the number of atoms for each element on both sides of the equation. In this case, we have:
Left side:
- Nitrogen (N): 3 atoms
- Hydrogen (H): 3 atoms
- Oxygen (O): 9 atoms
- Potassium (K): 1 atom
- Hydrogen (H) [from KOH]: 1 atom
Right side:
- Nitrogen (N): 2 atoms
- Oxygen (O): 6 atoms
- Potassium (K): 2 atoms
- Hydrogen (H): 2 atoms
- Oxygen (O) [from H2O]: 1 atom
2. Ensure that the number of atoms for each element is the same on both sides. In the given balanced symbol equation, the number of atoms is equal on both sides, so the equation is balanced.
Therefore, your proposed balanced symbol equation, 3HNO3 + 2KOH = 2KNO3 + H2O, is correct.
