Answer:
MgCl2 = 24 + 2(35.5)
= 95
mass of substance = mol × molar mass
= 0.119 × 95
= 11.305 g
Answer:
The second option
Explanation:
The process of elimiation.
1. We know liquids dont have a definite shape, they will morph into whatever enviroment theyre in
3. Solids dont expand based on what container theyre in, they either dont fit or they do
4. We know that liquid expands, so we can also rule this one out.
Which leaves us with option 2 to be correct.
Answer : The correct option is (B).
Explanation :
Body-centered cubic structure (bcc) :
Crystal structure : The manner in which the atoms or ions are spatially arranged.
In bcc arrangement, the atoms are present at eight corners of the cube and at the center of the cube. And the coordination number is 8.
Each unit cell has atoms at the corner and 1 full atom at the center of the cube.
Therefore, the each unit cell has atoms.
Image of bcc structure is shown below.
