liquid water at 50 °c is heated to steam at 150 °c. which piece of information is not required to determine the amount of heat that must be added for this change to occur?

Iknow the answer to 13 is b and 14 is d. i just need to know why the correct answers are correct

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.
