6. Calculate the wavelength of light emitted from Cas A due to the presence of Calcium. Show all work, use units, and apply rules of sig figs.
(Conversion factor: 1 eV = 1.60218x 10^-19J)

What are the 4 phases of matter in order of increasing engery content?

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.

Is this correct if not can u correct me
