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

Answer

B) associative property of addition

Explanation

The associative property states that you can add or multiply regardless of how the numbers are grouped.

For example:

3 + 5 = 8

5 + 3 = 8

Both equations are giving you 8 as the answer. This is called associative property of addition.

∴ 5 + 3w + 2 = 5 + 2 + 3w ⇒ represent the associative property of addition.
