Use the born-haber cycle to calculate the standard enthalpy of formation (δh > ) for licl(s) given the following data: δh(sublimation) li = 155.2 kj/mol i 1 (li) = 520 kj/mol bond energy (cl–cl) = 242.7 kj/mol ea (cl) = 349 kj/mol lattice energy (licl(s)) = 828 kj/mol

Astudent is trying to create a table that compares hypotheses, theories, and laws. hypothesis theory law do scientific researchers formulate it? yes yes yes does it explain why things happen? yes yes no yes yes yes is it used to make predictions? no yes yes which of the following questions would most likely fill the blank in the table? is it an intelligent guess? is it newly formulated? is it based on observations? has it been proved?
