An equal number of moles of i2(g) and br2(g) are placed into a closed container and allowed to establish the following equilibrium:
i2(g) + br2(g) 2ibr(g)
keq = 280
which one of the following relates [ibr] to [i2] at equilibrium?
[i2] = [ibr]
[i2] < [ibr]
[i2] = 2 [ibr]
[i2] = 280 [ibr]

Compare and contrast the bohr model and the electron cloud models of the atom.

Calculate the ratio of h+ ions to oh– ions at a ph = 7. find the concentration of h+ ions to oh– ions listed in table b of your student guide. then divide the h+ concentration by the oh– concentration. record this calculated ratio in table a of your student guide. compare your approximated and calculated ratios of h+ ions to oh– ions at a ph = 7. are they the same? why or why not? record your comparison in table a. what is the concentration of h+ ions at a ph = 7? mol/l what is the concentration of oh– ions at a ph = 7? mol/l what is the ratio of h+ ions to oh– ions at a ph = 7? : 1

If i initially have a gas at a pressure of 12 atm, a volume of 23 liters, and a temperature of 200 k, and then i raise the pressure to 14 atm and increase the temperature to 300 k, what is the new volume of the gas?
