Rank the following ionic compounds in order of decreasing magnitude of lattice energy (i. e., the absolute value of the lattice energy with the smallest magnitude listed last): aln, kbr, li2o, licl kbr > licl > li2o > aln aln > licl > li2o > kbr aln > li2o > kbr > licl aln > li2o > licl > kbr licl > kbr > li2o > aln

it’s previous models   because when i picked that son of a gun’s answer it was wrong look for previous models because they might make it a different letter  

hey there!

mass = 6.75 g

volume =   9 cm³

therefore:

d = mass / volume

d   = 6.75 / 9

d = 0.7 g/cm³

answer b

chemical changes occur when a substance combines with another to form a new substance, called chemical synthesis or, alternatively, chemical decomposition into two or more different substances. these processes are called chemical reactions and, in general, are not reversible except by further chemical reactions. some reactions produce heat and are called exothermic reactions and others may require heat to enable the reaction to occur, which are called endothermic reactions. understanding chemical changes is a major part of the science of chemistry.
