Certainly! We are tasked with completing the neutralization reactions by finding the missing components. Let's break down each reaction step-by-step:
### Reaction 1
[tex]\[ \text{HBr} + \text{KOH} \rightarrow \_ + \text{H}_2\text{O} \][/tex]
- Here, Hydrobromic acid (HBr) reacts with Potassium hydroxide (KOH) which is a base.
- In a typical neutralization reaction between an acid and a base, they produce a salt and water.
- The salt formed is usually composed of the cation from the base (K^+) and the anion from the acid (Br^-).
So the complete reaction is:
[tex]\[ \text{HBr} + \text{KOH} \rightarrow \text{KBr} + \text{H}_2\text{O} \][/tex]
### Reaction 2
[tex]\[ \text{H}_2\text{SO}_4 + \longrightarrow \left(\text{NH}_4\right)_2\text{SO}_4 + 2 \text{H}_2\text{O} \][/tex]
- In this case, sulfuric acid (H_2SO_4) is reacting and producing ammonium sulfate [tex]\(\left(\text{NH}_4\right)_2\text{SO}_4\)[/tex] and water.
- To form ammonium sulfate, we need ammonium hydroxide ([tex]\(\text{NH}_4\text{OH}\)[/tex]) as the base.
So the complete reaction is:
[tex]\[ \text{H}_2\text{SO}_4 + 2 \text{NH}_4\text{OH} \rightarrow \left(\text{NH}_4\right)_2\text{SO}_4 + 2 \text{H}_2\text{O} \][/tex]
### Reaction 3
[tex]\[ + \text{Mg(OH)}_2 \rightarrow \text{Mg(NO}_3\text{)}_2 + 2 \text{H}_2\text{O} \][/tex]
- In this case, magnesium hydroxide [tex]\(\text{Mg(OH)}_2\)[/tex] reacts to form magnesium nitrate [tex]\(\text{Mg(NO}_3\text{)}_2\)[/tex] and water.
- The corresponding acid that would react with [tex]\(\text{Mg(OH)}_2\)[/tex] to form [tex]\(\text{Mg(NO}_3\text{)}_2\)[/tex] is nitric acid ([tex]\(\text{HNO}_3\)[/tex]).
So the complete reaction is:
[tex]\[ 2 \text{HNO}_3 + \text{Mg(OH)}_2 \rightarrow \text{Mg(NO}_3\text{)}_2 + 2 \text{H}_2\text{O} \][/tex]
## Summary:
1. [tex]\[ \text{HBr} + \text{KOH} \rightarrow \text{KBr} + \text{H}_2\text{O} \][/tex]
2. [tex]\[ \text{H}_2\text{SO}_4 + 2 \text{NH}_4\text{OH} \rightarrow \left(\text{NH}_4\right)_2\text{SO}_4 + 2 \text{H}_2\text{O} \][/tex]
3. [tex]\[ 2 \text{HNO}_3 + \text{Mg(OH)}_2 \rightarrow \text{Mg(NO}_3\text{)}_2 + 2 \text{H}_2\text{O} \][/tex]
These are the complete formulas for the neutralization reactions.
