Answer 1

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.

$Na_{3}PO_{4}+KOH\rightarrow NaOH+K_{3}PO_{4}$

The balanced chemical reaction is as follows.

$Na_{3}PO_{4}+3KOH\rightarrow 3NaOH+K_{3}PO_{4}$

In the above reaction two reactants are exchange their cations. Therefore, it is a double displacement reaction.

2)

$Na_{3}PO_{4}+3KOH\rightarrow 3NaOH+K_{3}PO_{4}$

In the above reaction left side of the reaction is considered as reactants.

$Na_{3}PO_{4}$ - Trisodium phosphate

$KOH$ - Potassium hydroxide

3)

$Na_{3}PO_{4}+3KOH\rightarrow 3NaOH+K_{3}PO_{4}$

In the above reaction right side of the reaction is considered as products.

$NaOH$ - Sodium hydroxide

$K_{3}PO_{4}$ - Potassium phosphate.
