IT would be helpful to know what is in the data tables. But of more concern, you ought to know what you are doing in a lab before you start, so that you have an idea of what is the purpose, what data you will collect, and how to analyze it. I am quite certain you did not do th...

As I visualize the ring, current flows up each side from the bottom to the top. The current in each side of the ring is the same, flowing upward. Wouldn't the magnetic field in the ring at the center (ie y axis) exactly from the two sides exactly be in opposite directions,...

135Xe that does not capture a neutron decays to Cs-135, one of the 7 long-lived fission products, while 135Xe that does capture a neutron becomes stable 136Xe. Estimates of the proportion of 135Xe during steady-state reactor operation that captures a neutron include 90%,[6] 3...

and the denominator by 8, ... What does that mean? increase, multiplied, or what?

I am not certain if I understand the question. vapor pressure indicates the tendency for molecules to move to the vapor state. If forces bind the molecules together, bp will be highter, and for a given temperature, vapor pressure is lower. If forces disperse molecules, bp is l...

2H2+O2>>2H2O They should have gotten 1.01liters of water vapor, or 1/22.4 * 18 grams. as the vapor condenses, and cools to 25C, the H+ concen will be 1*10^-7 moles/liter Milliliters of product? One has to have the temp and pressure.
