In the given equation \( \text{B} + \text{H}_2\text{O} \rightarrow \text{BH}^+ + \text{OH}^- \), there are some initial reactants and products.
Let's analyze the equation:
Reactants:
- 1 particle of B
- 1 molecule of \( \text{H}_2\text{O} \) (which consists of 2 hydrogen atoms and 1 oxygen atom)
Products:
- 1 particle of \( \text{BH}^+ \)
- 1 particle of \( \text{OH}^- \)
Now, let's count the total number of particles before and after the reaction:
Total particles before the reaction:
- 1 (B) + 1 (H₂O) = 2 particles
Total particles after the reaction:
- 1 (BH⁺) + 1 (OH⁻) = 2 particles
Conclusion:
The total number of particles remains the same before and after the reaction. There are 2 particles on each side of the equation. Therefore, the number of particles does not change as a result of this reaction.
