Answer:
The answer to your question is 30 ml of H₂SO₄
Explanation:
Data
the volume of H₂SO₄ = ?
[H₂SO₄] = 0.6 M
volume of NaOH = 90 ml
[NaOH] = 0.4
Process
1.- Write the balanced chemical equation
H₂SO₄ + 2NaOH ⇒ Na₂SO₄ + 2H₂O
2.- Calculate the moles of NaOH
Molarity = moles/volume
moles = Molarity x volume
-Substitution
moles = 0.4 x 0.09
-result
moles = 0.036 of NaOH
3.- Calculate the moles of H₂SO₄
1 mol of H₂SO₄ ---------------- 2 moles of NaOH
x ----------------- 0.036 moles of NaOH
x = (0.036 x 1)/2
x = 0.018 moles of H₂SO₄
4.- Calculate the volume of H₂SO₄
Volume = moles / Molarity
-Substitution
Volume = 0.018 / 0.6
-Result
Volume = 0.03 ml or 30 ml
Molar solubility is number of moles of the solute that can be dissolved per liter of solution before the solution becomes saturated.
The molar solubility of lead(ii) chloride with ksp value of 2.4 × 10e4 can be solve as:
Ksp = s2 = 2.4 × 10e4
s2 = 2.4 × 10e4
s = √(2.4 × 10e4)
s = 154.9 mol/L
It’s, D. Kinetic Energy.
Explanation: Energy associated with an object’s motion is called kinetic energy. A speeding bullet, a walking person, and electromagnetic radiation like light all have kinetic energy.
Hope this helped ;)
