The KWL chart is a perfect model that could assist the student in the learning of science.
<h3>What the KWL chart?</h3>
The KWL chart is a perfect model that could assist the student in the learning of science. In this model, the student has to note down what he/she already knows about the experiment that is going to be performed. The notes in another column the wonders that he/she hopes to unravel during the course of the experiment and in the last column the student has to fill what he/she has learned after the experiment.
Having said that, if I want to leant about water, I already know that the molecules of water are in constant random motion according to the kinetic molecular theory so I write that down.
Secondly, I wonder how these water molecules actually move. If i drop a pollen grain i water and observe the zigzag motion of the pollen grain due to the bombardment of the water molecules, I can now write that I have learnt that the molecules of water move in a zig zag manner.

Answer: A) 0.20 L
Explanation:
Molarity of a solution is defined as the number of moles of solute dissolved per Liter of the solution.
According to the neutralization law,
where,
= molarity of stock solution = 10.0 M
= volume of stock solution = ?
= molarity of dilute solution = 0.50 M
= volume of dilute solution = 4.0 L
Therefore, the volume of 10.0 M solution needed to prepare 4.0 L of 0.50 M is 0.20 L
