How many atoms and elements in the problem bellow 10 Mg(OH)2 ( 3.08 < so i keep track of which assignment this question belongs to )

Acycloalkane molecule contains 8 carbon atoms. how many hydrogen atoms are present in the molecule?

Nonmetal halogen family atmoic mass 35

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.
