Consider the hydrate below.

fecl3•6h2o

which part of the formula comes first in the name of the compound?
-the term hydrate
-the anhydrous compound
-the prefix for the coefficient of water
-the physical state of the compound

May someone me with these science questions

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.
