Calculate the mass percent of nacl in a solution containing 3.00 g of nacl in 50.0 g of water.

The enthalpy of formation of water is -285.8 kj/mol. what can be inferred from this statement?

Asubstance is a good conductor of electricity which of the following best explains a probable position of the substance in a periodic table

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.
