EXPERIMENT: STATIC ELECTRICITY OBJECTIVES

Perform an experiment of ionic bonding.



Instructions

1. Suspend two inflated balloons by threads and tie them to a piece of string at the same point.

2. Rub each balloon with a piece of material.

A. What happens to the balloons when they are close together? What does this mean about their charge?

3. Cut two 3-by-12 inch strips of material from the nylon stocking.

4. Place both strips on a piece of white paper and rub them briskly in your hand.

5. With your fingers, lift the two pieces of nylon and hold them side by side.

B. What happens and why?

C. What electrical charge is present on the nylon strips?

6. Now bring one of the nylon strips near one of the balloons.

D. What happens? Explain what this means about the electrical charge of the nylon strip.

E. How does this investigation demonstrate the concept of ions and ionic bondi

1. use youre data the one which you made the highest points copy exactly that and write why you got that & how

2. what option did u choose and what did they tell u how it impacted the place.

3. i would set rules every friday we would clean up and every wensday we will protect endardged animals etc. hoped i

good luck

explanation:

i still can't find this

the framers of the constitution insisted that federal judges be nominated instead of elected due to their desire to have judges above the shifting whims of the masses.

the hope, whether achieved or not, was that federal judges would only be beholden to the law and that by not having judges be elected, they would be protected if that law dictated an outcome that ran counter to popular opinion.

the dna of humans and mice is almost 92% similar. this similarity indicates that . mice have a tail, while humans have a tailbone. the tailbone is a structure in humans.yes it's true.
