Complete the balanced molecular chemical equation for the reaction below. BaS(aq)+Sn(NO3)(aq)

How much mass would a mole of hydrogen molecules contain? recall that hydrogen is diatomic. g/mol

An electron moved from a lower energy level to a higher energy level. what most likely happened during the transition? a random amount of light was released. a fixed amount of energy was absorbed. a fixed amount of energy was released. a random amount of light was absorbed.

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
