Why is it that when I have a very small amount of acetylene in a test tube and have a small flame by it so oxygen will react with it, there is a popping sound.

This is complete combustion

The magnitude of each of the charges in the figure is 9.00x 10^-12 C. The lengths of the sides of the rectangle are 3.00 cm and 6.00 cm. Find the magnitude of the electric field at the center of the rectangle in figures a and b.
figure a N/C
figure b N/C

I have tried multiple ways of solving this problem to no avail. I am using coulomb's law to find the electric field (E=(kq)/r^2 and am not getting the right answer.

Here's what I'm doing:

E= ((8.99x10^9)(9.00x10^-12))/(.06708^2)

I obtained the radius using the pythagorean theorem.

Any help that anyone can offer would be greatly appreciated.

How Smart is Your Right Foot?
I bet that you cannot do this.

1. While sitting at your desk, lift your right foot
off the floor and make clockwise circles.

2. Now, while doing this, draw the number "6" in the
air with your right hand. Your foot will change
direction.


WHAT DO YOU THINK IS GOING ON?

(For those who claim that they can do this, are you drawing the number "6" from top of the 6 or from the inside out? Play fair now).

I need to get the names of these chemical formulas. btw, the numbers are suppose to be subscripts.

MgCl2----------Magnesium Chloride

Ag3P------------Silver Phosphoride

AlP---------------Aluminum Phosphoride



theres those other name endings like these: -ate, ide, ite, um.
when do i know which ending to use? btw, are my answers correct so far?
