I'm having issues finding information on the WWW about compounds of these elements for some reason, so I would love whatever help I can get, thanks in advance!

I think the answer is no, but I'm not sure to write this as an answer for biology class.

1. How do you find the number of protons, nuetrons and electrons in an isotope? If someone could show me a formula I am sure I could figure it out.
Specifically 207Pb, 16O(o not zero), 40K, 137Cs, and 40Ar? (numbers should be superscript)

2. How do you find the number of electrons in a specific element? Aluminum and Mercury would be great examples.

Thank you in advance, I have not taken a science class in about 15 years and it is like reading greek to me.

How much heat is absorbed when 5 grams of water is heated from 12 C to 24 C? The specific heat of water is 1 cal/gxC

I just completed a lab where we measured the specific heat of a metal. During the lab, we had to measure the temperature of boiling water. Why did we have to do this? Shouldn't boiling water be at exactly 100'C?

I did an experiment in chem class in which i found the mass of a sealed flask with air in it, then replaced the air with oxygen and found the mass of that. The mass of the flask + O2 is less than just the flask. Did i do something wrong?

I am making a drinking apparatus for a party. I have punch in a bowl. It is siphoned from there through a small rubber hose. That hose drains into a glass beaker with a burret on the bottom that the kids can turn on and off to get the punch out of the beaker. The problem is that the punch fills up the beaker and doesnt stop. HOW do i make it stop and fill up only part of the beaker? Any ideas please help!
