Where do i lithium iodide has a lattice energy of −7.3×102kj/mol and a heat of hydration of −793kj/mol. find the heat of solution for lithium iodide. determine how much heat is evolved or absorbed when 10.0g of lithium iodide completely dissolves in water.

Look at the spectrums of a star moving towards earth and a motionless star. which of these is a correct inference that can be draw from the observation of the two spectrums?
