You are given metal bar that has “1 mole of" written on it, but you can't tell what it says to know what the metal is. You put the 1 mole bar on the scale. The metal bar weighs 51.996 grams. What metal is this?

How many moles of air are there in a human lung with a volume of 2.4 l at stp? explain your answer

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.
