Why does a solid change to liquid when heat is added?
the spacing between particles decreases.
particles lose energy.
the spacing between particles increases.
the temperature decreases.

One of the cell membrane's functions is to protect the cell keep wastes in the cell create new cells keep light out of the cell

Matches the chemical name of each oxide of phosphorus to its chemical formula

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.
