<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.

Maybe because someone hasn't been swimming on tht side bacause the water changes it's tempurture from your body heat or maybe because it isnt any sun out
<h2>
Answer: 448254.609 mm³ OR 4.48 × 10⁵ mm³ </h2>
Explanation:
Volume = Mass ÷ Density
= 0.08 g ÷ 0.17847 g/L
= 0.448254609 L
since 1 L = 1,000,000 mm³
then 0.448254609 L = 448254.609 mm³
3 N
10-7= 3

Answer:
1.46 moles NaCl
Explanation:
To find the moles of NaCl, you need to multiply the given value (0.731 moles BaCl₂) by the mole-to-mole ratio of the two relevant molecules. This ratio is made up of the coefficients in the balanced reaction. The numerator should contain moles NaCl to allow for the cancellation of moles BaCl₂. The final answer should have 3 sig figs to reflect the given value.
1 BaCl₂(aq) + Na₂SO₄(aq) ---> BaSO₄(s) + 2 NaCl(aq)
0.731 mole BaCl₂ 2 moles NaCl
--------------------------- x ------------------------- = 1.46 moles NaCl
1 mole BaCl₂
