Answer:
1. Double displacement reaction
2. Trisodium phosphate and potassium hydroxide
3. Sodium hydroxide and Potassium phosphate
Explanation:
1)
The given chemical reaction is as follows.
[tex]Na_{3}PO_{4}+KOH\rightarrow NaOH+K_{3}PO_{4}[/tex]
The balanced chemical reaction is as follows.
[tex]Na_{3}PO_{4}+3KOH\rightarrow 3NaOH+K_{3}PO_{4}[/tex]
In the above reaction two reactants are exchange their cations. Therefore, it is a double displacement reaction.
2)
[tex]Na_{3}PO_{4}+3KOH\rightarrow 3NaOH+K_{3}PO_{4}[/tex]
In the above reaction left side of the reaction is considered as reactants.
[tex]Na_{3}PO_{4}[/tex] - Trisodium phosphate
[tex]KOH[/tex] - Potassium hydroxide
3)
[tex]Na_{3}PO_{4}+3KOH\rightarrow 3NaOH+K_{3}PO_{4}[/tex]
In the above reaction right side of the reaction is considered as products.
[tex]NaOH[/tex] - Sodium hydroxide
[tex]K_{3}PO_{4}[/tex] - Potassium phosphate.
