<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:
C. Tip had the lower pressure, it was 652.71mmHg
Explanation:
To answer this question you need to convert both values into a common unit so you can compare directly.
87kPa = 652.71 mmHg
Answer:
Percentage of carbon of alkene is higher compared to the alkane that has the same number of carbon per molecule. Because of this, combustion of alkene will produce more sooty flame compared to their corresponding alkane and because Alkenes have a higher percentage of carbon compared to their corresponding alkane.
Explanation:
Relative atomic mass : C= 12 and H=1
Percentage of Carbon Hexane (C6H14)
Percentage of Carbon = 83.7 percent
6(12) x 6(12) +14(1) x 100 percent= 83.7 percent
Percentage of Carbon Hexene = 85.7 percent
Answer:
Option D is good to go!
Explanation: as per the reactivity series more reactive substances will react with the counterpart substance.The most reactive substance here is calcium while the least reactive is aluminium, the magnesium comes in between.As per their reactivity, these substances will react with oxygen.
Explanation:
Answer:
Hexane is a 6-carbon hydrocarbon.
Cyclopentyl is a 5-carbon, hydrocarbon ring.
The 1- indicates that the cyclopentyl is attached to the first carbon in hexane.
Two ways of drawing the structure of 1-cyclopentylhexane are below:
