After the initial experiment, students predicted that the type of material used on the surface of their experiment would also influence static friction. They set up an angled ramp and varied the surface material. The data from the second experiment can be seen aboveBased on both experiments, predict which combination, shoe plus surface, would have the greatest static friction

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.
