NEED HELP ASAP Calculate the equilibrium concentrations of H2, I2 and HI at 700.K if the initial concentrations are [H2] = 0.400M, [I2] = 0.400M. The equilibrium constant Kc for the reaction is 57.0 at 700K.

What is the temperature in kelvin of a gas if it is allowed to expand from 1.50 l to 4.50 l? the initial temperature is 10.0°c and pressure is constant throughout the change. which equation should you use? t2= v2/v1 t1 what is the final temperature? ⇒ 849 k these are the answers.

It takes 155. kj/mol to break a fluorine-fluorine single bond. calculate the maximum wavelength of light for which a flouine-flouring single bond could be broken by absorbing a single photon

Where do the numbers in a stoichiometry mole ratio come from
