Compute the energy separation in joules, kilojoules per mole, electron volts, and reciprocal centimeters between the levels (a) n = 3 & n = 1 (b) n = 7 & n = 6 of an electron in a box length 1.50 nm.
Carbonyl fluoride, COF2, is an important intermediate used in the production of fluorine-containing compounds. For instance, it is used to make the refrigerant carbon tetrafluoride, CF4 via the reaction
When a sample of H2S(g) (9.811 mol) is placed in 180.0 L reaction vessel at 724.0 K and allowed to come to equilibrium the mixture contains 0.01627 mol/L of S2(g). What is the equilibrium concentration (mol/L) of H2S(g)? 2H2S(g) = S2(g)+2H2(g)
