Hydrogen and oxygen react under a specific
set of conditions to produce water according
to the equation
2 H2(g) + O2(g) → 2H2O(g).
How much hydrogen would be required to
produce 3.5 mol of water?
Answer in units of mol.

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.
