1) Draw representations of both ionic solids in each set that show the relative differences in the sizes of the four ions, the ratio of cations to anions, and the charge on
each ion; identify which ionic solid will have the higher melting temperature; and justify
your answer. (Formula units that contain two ions must be drawn as networks consisting
of twelve ions in total. Formula units that contain more than two ions can be represented
as a single formula unit.)
NaCl or KBT
NaCl or MgS
BeF2 or LiF
CaO or CaCl2
MgO or Al2O3

Hannah is writing a report on how albedo affects the global climate. she’s proofreading her passage for any factual errors. which sentence must hannah correct before submitting her report? earth receives energy from the sun. this energy drives many of the processes on earth, including its climate. some part of this energy is reflected by earth’s surface. we use the term albedo to describe the reflected energy. albedo of an object is the ratio of the reflected radiation to the total radiation reaching the object. a value of 0 means no energy is absorbed by the object, whereas a value of 1 means that all of the energy is absorbed. in this way, the albedo of an object can influence earth’s atmospheric temperature.

Select the correct answer. which statement is true about a polarized object? o a. it gains electrons and becomes negatively charged. ob. it gains protons and becomes positively charged. oc. the number of positive and negative charges can be the same. od. it has to be a metal. o e. there is no change in the distribution of the charge in the object. reset next what
