rub the paper on the acetate (only in one direction)

Rub the acetate strip against the paper towel to transfer electrons from the acetate strip to the paper towel, leaving the acetate strip positively charged. Touch the electroscope's metal knob with the positively charged acetate strip to transfer the positive charge to the electroscope. This will cause the electroscope's leaves to repel each other, indicating a positive charge.

Suggest why the small peice of paper stick to the charged comb?
The small piece of paper sticks to the charged comb because of static electricity. When the comb gets charged by rubbing it against a material like fabric or fur, it gains excess electrons which create a negative charge. The negative charge on the comb attracts the positively charged protons in the paper, causing the paper to stick to the comb.
Why does a straw attract another straw when rubbed with piece of paper but repels it if it is rubbed with a sheet of paper?
When a straw is rubbed with a piece of paper, it acquires a positive charge due to the transfer of electrons from the paper. Two positively charged straws will repel each other. However, when a straw is rubbed with a sheet of paper, it acquires a negative charge, and opposite charges attract, resulting in the straws being attracted to each other.
What attracts the paper pieces to the balloon?
When the balloon is rubbed against hair or clothing, it gains a static electric charge. The paper pieces become attracted to the balloon due to this static electricity, which causes the positively charged balloon to attract the negatively charged paper pieces.
Why does tissue paper stick to a balloon when it has been rubbed by wool?
When the balloon is rubbed with wool, it gains a negative charge while the tissue paper remains positively charged. Opposite charges attract, causing the tissue paper to stick to the balloon. This is due to the transfer of electrons from the wool to the balloon, creating an electric charge imbalance between the two objects.
When a comb rubbed with dry hair why attracts small bits of paper?
When you rub a comb against dry hair, electrons from the hair are transferred to the comb, giving the comb a negative charge. The small bits of paper are attracted to the comb because they acquire a positive charge and are attracted to the negative charge on the comb due to electrostatic forces.
What happens when you rub an acetate strip with tissue paper and then hold the strip near running water?
If you rub an acetate rod with a cloth electrons are transferred from the rod to the cloth and the rod becomes negatively charged and the cloth becomes positively charged.
Which turns lead acetate paper black?
Hydrogen sulfide (H2S) turns lead acetate paper black. Lead acetate paper is used as a test for the presence of hydrogen sulfide gas. If the paper turns black upon exposure to a gas, it indicates the presence of hydrogen sulfide.
Can you buy acetate paper in magenta?
you can buy acetate paper {may be in magenta] in hero arts or go to. Or get it cheap in the American science and surplus i *think* the website is www.sciplus.com
Why is acetate paper see through?
Cuz the japanese are so poor all they could use was paper even as walls in their buildings. So they use acetate paper for windows. Then shower curtains. Then clothes... Etc. Im not joking

Is acetate is transparent?
Yes, acetate is transparent. It is the main ingredient used to make what is known as transparency paper. Transparency paper is often used to display printed images over an overhead projector. This is considered old technology.
Which makes the lead acetate paper black?
Lead acetate paper turns black in the presence of hydrogen sulfide gas. Hydrogen sulfide reacts with lead acetate to form lead sulfide, which is black in color. This reaction is commonly used as a test for the presence of hydrogen sulfide gas.
When a comb rubbed with dry hair why attracts small bits of paper?
When you rub a comb against dry hair, electrons from the hair are transferred to the comb, giving the comb a negative charge. The small bits of paper are attracted to the comb because they acquire a positive charge and are attracted to the negative charge on the comb due to electrostatic forces.
When you rub comb on dry hair why I t attracts small piece of paper?
When you rub a comb on dry hair, it generates static electricity. This static charge causes the comb to attract small pieces of paper because the paper bits become negatively charged, while the positively charged comb attracts them.
