It gets wet.
polymerisation. 2 monomers split to forn a polymer

It is around 1.8 decimetres.
Water can be separated into its component gases; Hydrogen and Oxygen. One of the easiest methods is using Electrolysis, by means of metal plates immersed in the water and connected to a DC power supply. Frequently, some other chemical is dissolved in the water, to create an Electrolyte, this is primarily used to reduce the resistance of the Cell, thereby increasing the current across it thus increase the output of these component gases.
There are 6.02 x 10^23 molecules per mole of any substance: this is 0.6 trillion trillion molecules.A mole of water is only 18 grams. A regular wood pencil weighs about half of that. There will be fewer molecules of wood but more atoms per molecule. But you are still talking a range of hundreds of billions of trillions of atoms (10^22) in an item the size of a pencil.
A Refracted image is like an illusion. Which fools the brain e.g. You see a pencil but the pencil has split in two parts.Demonstration:You will need: Glass, Pen or Pencil and WaterSteps:1. Put the glass on a table,2. Fill the glass to about 3/4 quarters of water,3. Put the Pen or Pencil in the glass of water,4. See what happens to the pencil.See, it seems to have split.
no, a pencil will float therefore it is less dense than water(ticonderoga #2 pencil was used)no pencils were harmed in the execution of this experiment
You split the water evenly into cups
To make smencils, you will need: Recycled Newspaper A pencil (OF COURSE) A cup of water a plastic plate or steel a lime, lemon, or orange Scissors 1. Cut out the newspaper into a medium sized piece, 2. Wrap the newspaper around the pencil. 3. Mix the water with the lemon juice. 4. Let the pencil soak in the water with the juice for some 2-3 hours. 5. Take out the pencil and put it on a plate. 6. Wait till all the newspaper is dry. TADA! You know have a scented pencil.
Usually on most pencils it says it on the case or on the side of the pencil by the eraser it says PENCIL #2 or #2.Hope i helped!:)

I don't quite understand what you mean by HB-2 pencil but if you mean HB pencil / #2 Pencil it is not the softest pencil. Pencils scale from 9H to 9B, (HB in the middle) and 9B would the softest and darkest pencil there.

It's softer. #1 softest, #2 slightly harder, #3 harder than #2, etc.Softer.a #1 pencil is softer than a#2 pencil
The 2 is the number of the lead in the pencil.
An HB pencil is just a No. 2 Pencil HB stands for Hard Black
It's spelled 'normal,' and it is a #2 pencil.
