K₃PO₄ → 3K⁺ + PO₄³⁻

PO₄³⁻ + H₂O ⇄ HPO₄²⁻ + OH⁻

HPO₄²⁻ + H₂O ⇄ H₂PO₄⁻ + OH⁻

H₂PO₄⁻ + H₂O ⇄ H₃PO₄ + OH⁻

K⁺, PO₄³⁻, HPO₄²⁻, H₂PO₄⁻, OH⁻

Answer : The balanced chemical equation will be:

(i) 2K+H_2SO_4\rightarrow K_2SO_4+H_2

(ii) Mg(OH)_2+Zn\rightarrow Zn(OH)_2+Mg

Explanation :

Balanced chemical equation : It is defined as the equation in which total number of individual atoms on the reactant side is equal to the total number of individual atoms on product side.

Part (i):

The balanced chemical equation will be:

2K+H_2SO_4\rightarrow K_2SO_4+H_2

This reaction is a single displacement reaction in which most reactive element (potassium) displaces the least reactive element (hydrogen) form their solution.

Part (ii):

The balanced chemical equation will be:

Mg(OH)_2+Zn\rightarrow Zn(OH)_2+Mg

This reaction is a single displacement reaction in which most reactive element (zinc) displaces the least reactive element (magnesium) form their solution.

Hunter-Best [27]

Answer: 3.75 M

Explanation:

400 mL = 0.4 L

NaOH has a molar mass of around 40 g/mol.

\frac{60 grams}{40 g/mol} = 1.5 moles

Molarity = \frac{1.5 moles}{0.4 Liters} = 3.75 M
