Answer: H_2SO_4(aq)+2KOH(aq)\rightarrow K_2SO_4(aq)+2H_2O(l)

Explanation:

Neutralization is a chemical reaction in which acid and base combine to form salt and water. Acids donate H^+ ions and bases donate OH^- ions in water which combine to form water molecules.

The balanced molecular equation is ;

H_2SO_4(aq)+2KOH(aq)\rightarrow K_2SO_4(aq)+2H_2O(l)

4 g of ag2so4 will dissolve in 1l of water. calculate the solubility product (ksp) for silver (i) sulfate.
Bas_tet [7]
Reaction of dissociation: Ag₂SO₄ → 2Ag⁺ + SO₄²⁻.
m(Ag₂SO₄) = 4 g.
V(Ag₂SO₄) = 1 l.
n(Ag₂SO₄) = m(Ag₂SO₄) ÷ M(Ag₂SO₄).
n(Ag₂SO₄) = 4 g ÷ 311,8 g/mol.
n(Ag₂SO₄) = 0,0128 mol.
n(Ag⁺) = 2 · 0,0128 mol = 0,0256 mol.
n(Ag₂SO₄) = n(SO₄²⁻) = 0,0128 mol.
c(Ag⁺) = n ÷ V = 0,0256 mol ÷ 1 l = 0,0256 mol/l.
Ksp = c(Ag⁺)² · c(SO₄²⁻).
Ksp = (0,0256 mol/l)² · 0,0128 mol/l.
Ksp = 8,3·10⁻⁶.

A vial of amoxicillin contains 500 mg in 2.0 mL of solution. What volume of the solution contains 180 mg of the drug
Tom [10]
<span>0.72 mL of solution will have 180 mg of amoxicillin. For this problem, you need to calculate the equivalent ratio of volume as to the ratio of amoxicillin. So 180/500 = X/2.0 Multiply both sides by 2 2 * 180/500 = X 360/500 = X 18/25 = X 0.72 = X So you need 0.72 mL of solution to get 180 mg of the drug.</span>
