HELP ME PLEASE I BEG Can someone explain what the heII lattiCE STRUCTURES ARE. WHY IS IT THAT NaCl HAS 27 ATOMS IN ITS STRUCTURE WHEN THE BALANCED MOLECULE HAS 2 ATOMS?? WHAT HAPPENS TO THE LAST ONE??? WHAT IS A CELL UNIT?? I THOUGHT CELLS WERE A BIO THING? PLEASE IM DESPERATE THIS IS ALL THE POINTS I HAD

please to all the kind souls out there, i just wanna pass chem ;-;

A lattice structure is a space-filling unit cell that can be tessellated along any axis with no gaps between cells. These structures are an emerging solution to weight, energy and advanced manufacturing time reduction

id k the second and third one

A unit cell is the smallest portion of a crystal lattice that shows the three-dimensional pattern of the entire crystal. A crystal can be thought of as the same unit cell repeated over and over in three dimensions

hope it helps this is all i can do

organisms are more likely to be more preserved in mud than sand because mud is moist and wet, while sand is very dry.

the number of valence electrons for each molecule or ion is shown beneath the structure. remember hydrogen will not have more than two electrons. this hydrogen is part of a covalent bond (sharing two electrons). a double bond here would cause hydrogen to share four electrons with phosphorus.
