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
Answer:
Here are the differences between the hot and cold water. The particles in the hot water move faster than the particles in the cold water.

Answer:
Explanation:
The electronic configuration of a lithium atom is 2.1 and that of a fluorine atom is 2.7
an atom of lithium donates an electron to an atom of fluorine to form an ionic compound. The transfer of the electron gives the lithium ion a net charge of +1, and the fluorine ion a net charge of -1.
It is d. compounds because they have more than one element.
Answer:
The enthalpy is increased by the increased heat of the reaction.
Explanation:
In this reaction, as the transition from solid to liquid state, enthalpy increases, that is, the heat applied to change its state is greater and this increases, reaching a mayor disorder.
If the reaction increases its heat, and a liquid state passes, the enthalpy increases, therefore the disorder also and the entropy will also be increased.
