The longest wavelength of light with enough energy to break the cl-cl bond in cl2(g) is 495 nm.
1) calculate the frequency in s-1 of the light2) calculate the energy in j of a photon of the light3) calculate the minimun energy in kj mol-1 of the cl-cl bond

There is one girl i like and i don't know how to tell her that, i have a feeling she knows but if she doesn't i don't want to make a fool out of myself how is one way to boost my confidence on asking her out

The table lists the lattice energies of some compounds. compoundlattice energy (kj/mol)lif            –1,036licl            –853naf            –923kf            –821nacl            –786which statement about crystal lattice energy is  best  supported by the information in the table? the lattice energy increases as cations get smaller, as shown by lif and kf. the lattice energy increases as the cations get larger, as shown by lif and licl. the lattice energy decreases as cations get smaller, as shown by nacl and naf. the lattice energy decreases as the cations get smaller, as shown by naf and kf.

What is the empirical formula of a compound that is 50.7% antimony and 49.3% selenium ?
