In an ionic compound, the size of the ions affects the internuclear distance (the distance between the centers of adjacent ions), which affects lattice energy (a measure of the attractive force holding those ions together). Based on ion sizes, rank these compounds of their expected lattice energy. Great Lateral Energy to least (weakest) lattice energy.
Nal
NaCl
NaBr
NaF
How much heat (in ) is required to warm 12.0 g of ice, initially at -11.0 degrees C, to steam at 111.0 degrees C? The heat capacity of ice is 2.09 and that of steam is 2.01 J/gC.
A reaction was conducted in benzene as the solvent. Because the reaction was very exothermic, the mixture was cooled in a salt-ice bath. This was a bad choice. Why?
