Consider the equilibrium N2(g)+3 H2(g) 2 NH3(g) at a certain temperature. An equilibrium mixture in a 4.00-L vessel contains 1.60 mol NH3, 0.800 mol N2, and 1.20 mol H2. What is the value of Kc?

A40 kilogram skier starts at the top of a 12 meter high slope. at the bottom, she is travelling 10 meters per second. how much energy does she lose to friction

The size (radius) of an oxygen molecule is about 2.0 ×10−10m. make a rough estimate of the pressure at which the finite volume of the molecules should cause noticeable deviations from ideal-gas behavior at ordinary temperatures (t= 300k ). assume that deviatons would be noticeable when volume of the gas per molecule equals the volume of the molecule itself.
