Consider the neutralization reaction 2hno3(aq)+ba(oh)2(aq)⟶2h2o(l)+ba(no 3)2(aq) a 0.105 l sample of an unknown hno3 solution required 29.1 ml of 0.200 m ba(oh)2 for complete neutralization. what is the concentration of the hno3 solution?

Iknow #2 is d. i just need to know why

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.
