Draw the hydrogen bonds between the bases. the letter r represents the rest of the nucleotide. the bases are positioned approximately as they would be in a dna double helix. to indicate a hydrogen bond, simply draw a regular single bond between the atoms. be careful not to modify the existing atoms or bonds in any way, not add extraneous atoms or bonds.

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.
