Consider this equilibrium: h2(g) + i2(g) 2hi(g) keq = 50.0. what is the keq value when the reaction rewritten: 2hi(g) h2(g) + i2(g) keq = ?

When electrolyzing copper (ll) chloride, what reaction takes place at the anode? what reaction takes place at the cathode?

In a ni-cd battery, a fully charged cell is composed of nickelic hydroxide. nickel is an element that has multiple oxidation states. assume the following proportions of the states: nickel charge proportions found 0 0.17 +2 0.3 +3 0.33 +4 0.5 (a) determine the mean of the nickel charge. enter the answer to 2 decimal places.(b) determine the cumulative distribution function of nickel charge.

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.
