I have 2 questions about precipitate reactions...

1) Why do some combinations of ionic compounds form a precipitate while others don't?

2) What is the molecular equation for the combination of Lead(II) Nitrate and potassium iodide?

Thanks for your help, and even if you can only answer 1 question, I still appreciate it!

Hawking has an extendible boxing glove attached to his chair which he operates with his eye or summat or nuffin.

Whilst Dawkins has his "hatred of religion" weapon on his side.

Ding Ding, round one..

It was a multiple choice, so maybe you can't work it out normally but it was:
[Integral from -1 to 1] (2-e^x)/(1+e^x) dx

a) 0
b) 1
c) ln 2
d) e

My guess is that it will be ln 2 but i'm not sure. How do you do this?

I tried using a trend line, but that doesn't have an option to fit to trig functions. I'm trying to create a laboratory exercise for my (college) students to do, and I'd rather have them use the computer to fit the data than do it by hand.

They are all about triangles =D

1.) If a triangle has two angles of equal measure, then the third angle is obtuse.

2.)If two sides and a non-included angle of a triangle are congruent to two sides and a non-included angle of another triangle, then the triangles are congruent.

3.)If the measure of an exterior angle of a triangle is 45 degress, then each of the corresponding remote interior angles also has a measure of 45 degress.

I heard under the microscope they look the same. Also heard that during the blood shortage following 9-11. There was talk of using clean sea water mixed with blood to stretch the supply.
